[Question]
  [
[Deadfish](http://esolangs.org/wiki/Deadfish) is one of the best known non Turing-complete programming languages. It has only one accumulator (which starts at 0) to store data, and only four commands:
```
i - Increment the accumulator
s - Square the accumulator
d - Decrement the accumulator
o - Output the accumulator
```
A Deadfish program may look like:
```
iiisdo
```
And that would print:
```
8
```
---
# The challenge
Create a program that will input a number and output Deadfish code to display the number.(Or make a function that takes the number as a parameter and returns the code.) It must work for any integer from `0` to `255`
## Goal
Try to make your code make the shortest code possible to generate the given number. For example:
```
iiiiiiiiio
```
and
```
iiiso
```
each print `9`, but the second is shorter.
# Scoring
Your score is:
```
The number of characters in your source code +
The sum of the lengths of your output for all numbers from 1-255
-100 if the language you chose is Deadfish :)
```
Lowest score wins!
---
In the original challenge I only had the sum of 6 numbers(9,17,99,100 and 123).
This was from me wanting to not make everyone test for every number, and I wanted the shortest code to be relevant. Then I realized that programmers are good at making scripts to test things like that, and I would rather have this be a contest for best algorithm with golfing as a tiebreaker.
Therefor I changed this, as suggested by Martin Büttner.

# ES6 JavaScript 2126 + 311 = 2437 score
```
m=Math;s=n=>[b=m.min(m.sqrt(n)+.5|0,15),n-b*b];f=n=>(n<0?'d':'i').repeat(m.abs(n));g=(n,t)=>n<4?f(n):g((t=s(n))[0])+'s'+f(t[1]);q=n=>((x=g(n)).length>(z=[...n+''].map((k,i,a)=>i?(a[i-1]==a[i]?'':(y=f((l=s(k))[0]-a[i-1])+(l[0]?'s':'')+f(l[1])).length>m.abs(Q=a[i]-a[i-1])?f(Q):y):g(k)).join('o')).length?z:x)+'o'
```
Semi-commented:
```
m = Math; // Keep a reference to math
// This function returns the closest perfect square and the distance from that square to the number
// E.g. s(10) --> [3, 1] because 3^2 + 1 = 10
s = n => [b = m.min(m.sqrt(n) + .5 | 0, 15), n - b * b];
// This creates a bunch of "d"s or "i"s
// E.g. f(3) --> "iii" or f(-2) --> "dd"
f = n => Array(m.abs(n) + 1).join(n < 0 ? 'd' : 'i');
// This constructs the number as a number rather than by digit
g = (n, t) => n < 4 ? 
              // If n is less than 4, then we can just increment in normally (base case)
              f(n) : 
              // Otherwise, build the square root recursively and shift
              g((t = s(n))[0]) + 's' + f(t[1]);
// This maps based on digits (constructs the number by digit)
// This has now been removed and replaced inline because it is only used once
d = n => (a = [...(n + '')]).map((k, i) => i ? (a[i - 1] == a[i] ? '' : f((l = s(k))[0] - a[i - 1]) + (l[0] ? 's' : '') + f(l[1])) : g(k)).join('o');
// For the official function, compare the digit-method and nondigit-method and return the best one
q = n => ((x = g(n)).length > (z = d(n)).length ? z : x) + 'o'
```
This takes advantage of the fact that in deadfish, you can print more than one character.
Example: `10` compiles to `iodo` which is "print one, decrement, print zero."
Usage:
```
q(10) // --> iodo
q(16) // --> iisso
```
Here's json data of output:

    "255": "iiosioo"
}
```
That was generated by this code:
```
var c = {}, result = 0;
for (var i = 0; i <= 255; ++i) result += (c[i] = q(i)).length;
```
which prints `result = (the result)` and `c =` the thing above.
This gets a remarkably high score despite being pretty simple. It searches for the nearest perfect square, calculates the square root of that perfect square, adds 's', and increments/decrements appropriately.
Old version which didn't use the fact that "10" = "print one, print zero"
```
m=Math;s=n=>[b=m.sqrt(n)+.5|0,n-b*b];f=(n)=>Array(m.abs(n)+1).join('id'[+(n<0)]);g=(n,t)=>n<4?f(n):g((t=s(n))[0])+'s'+f(t[1]);q=n=>g(n)+'o'
```
[Answer]
# Haskell, ~~2200~~ ~~2177~~ 2171 = 2036 + 135
```
f n=[s|s<-l,s%0==show n]!!0
l="":[c:x|x<-l,c<-"iosd"]
(h:s)%n|h<'e'=s%(n-1)|h<'j'=s%(n+1)|h<'p'=show n++s%n|n==16=s%0|0<1=s%(n^2)
x%_=x
```
this works by having an infinite list of all deadfish programs, sorted by their length, accompanied by the internal state and the output. the function `f` searches the list and returns the first entry that matches.
this approach allows for for multiple `o` in each resulting code, but does not restrict it to either printing all the digits separately, or printing the whole number at once. for example, here 216 has the code of `iiosso`.
**Edit:**  
according to the spec, when the state is 256 (but not 257) it is made into a 0. now my code takes this into account. for example, 160 is `iissoso`.
this has a few efficiency problems; because `l` is a top-level list, all the elements of `l` which have been evaluated stay in memory, and so runtime will probably be out of memory at some point.
to calculate the score, I made an equivalent-but-less-memory-heavy version.
my more-efficient code works by recomputing the list on every application of `f`, so that the garbage collector can throw the already searched part of the list away. in a sense, this is breadth-first search using laziness.
the more-efficient code also adds some more constraints to the elements of the list - it filters out all codes that contain `id` or `di`, or contains an `s` when the state is smaller than 2.
**Edit:**  
I moved the `g` function from the top level to being a helper function to
`f'`, so now `g` filters codes that printed something which isn't a prefix of our wanted number. now the code is much faster.
the more-efficient code:
```
f' n=[reverse s|(s,_,r)<-l,r==show n]!!0 where
    l=("",0,""):l>>= \(i,s,r)->filter g[('i':i,s+1,r),('o':i,s,r++show s),('s':i,if s==16 then 0 else s*s,r),('d':i,s-1,r)]
    g('i':'d':_,_,_)=False
    g('d':'i':_,_,_)=False
    g('i':'i':_,4,_)=False
    g('s':_,1,_)=False
    g("s",_,_)=False
    g("si",_,_)=False
    g(i,s,r)=s<256&&s>=0&&isPrefixOf r (show n)
```
note the more-efficient code will not have the same results because the programs traverse all the possible codes in different order. however, they will output codes of the same length. also, switching `c:x` with `x++[c]` makes the programs equivalent.
with this code i was able to compute all the programs in ~~52~~ 0.81 seconds.
**Edit:**  
apparently this is the best answer! i noticed it just now, so far from when this was asked...

## Mathematica, ~~254~~ 165 characters + 3455 = 3620
```
f@n_:=n;g@0="";l={f@0=0};h=If[f@#>f@i&&#<256&&#>0,f@#=f@i+1;g@#=g@i<>#2;l~AppendTo~#]&;While[l!={},i=#&@@l;l=Rest@l;h[i+1,"i"];h[i-1,"d"];h[i*i,"s"];];g@Input[]<>"o"
```
Less golf:
```
f@n_ := n;
g@0 = "";
l = {f@0 = 0};
h = If[f@# > f@i && # < 256 && # > 0,
    f@# = f@i + 1;
    g@# = g@i <> #2;
    l~AppendTo~#] &;
While[l != {},
  i = # & @@ l;
  l = Rest@l;
  h[i + 1, "i"];
  h[i - 1, "d"];
  h[i*i, "s"];
  ];
g@Input[] <> "o"
```
I believe the resulting numbers are optimal. This is doing a breadth-first search over all 256 numbers, keeping track of the shortest way it has found to represent each number. The search is building a sort of lookup table in the function `g` which is then applied to the input.
For reference, here are all 255 results:

[Answer]
## C, 433 code + 3455 output = 3888
## C++, 430 code + 3455 output = 3885
And now for something completely different.
I used the output from [Martin's Mathematica answer](https://codegolf.stackexchange.com/a/40126/32254) (updated on October 23rd as it was wrong for 240+ before). My output is the same 3455 characters. I analyzed patterns in the output and discovered that [0,255] can be represented by this sequence:
1. 0-3 `i`s
2. 0-2 `s`s
3. 0-3 `i`s or `d`s
4. 0-1 `s`s
5. 0-14 `i` or 0-16 `d`s
6. 1 `o`
The next step was to carefully construct these five columns (`c` through `g` in the code below). I used negative numbers to indicate `d` instead of `i` in columns `e` and `g`. Then, it turns out that the results work mostly like a counter in the `g` column, since each row `u` usually removes one `d` or adds one `i` relative to the previous row (`v`). There are 15 exceptions, which are stored in `x` (the indexes) and `b` (the five columns, packed into an integer which only requires 14 bits to store the maximum `10832`).
For example, the first "exception" is the very first row, where we want zero characters apart from the terminating `o`. So `x[0]` is `0`, and `b[0]` is `544`, which when unpacked is ("little endian" style, since `g` is the counting column) `{ 32, 0, 4, 0, 0 }`. We always subtract 32 from `g` and 4 from `e` to make the unsigned bit-fields work (i.e. those two columns represent negative numbers conceptually when `d` is required instead of `i`, but in the implementation the values are offset to avoid actual negative numbers).
Here's a table showing how the first ten numbers work (blanks are zeros):
```
n   text    c   d   e   f   g
0   o                   
1   io                      1
2   iio                     2
3   iiio                    3
4   iiso    2   1           
5   iisio   2   1           1
6   iisiio  2   1           2
7   iisiiio 2   1           3
8   iiisdo  3   1          -1
9   iiiso   3   1           
```
You can see that `g` mostly just increments by one for each new row, but some rows (0, 4, 8, ..., which I briefly hoped to find in OEIS) "reset" the sequence, meaning `g` takes on some new value and at least one other column is modified as well.
The code character count excludes whitespace except the mandatory newline before each `#` and space after `unsigned` and `int`. You can save 3 characters by compiling as C++ instead of C, replacing `<stdio.h>` with `<cstdio>`, and `*(int*)&u` with `(int&)u`.
```
#include <stdio.h>
struct { unsigned g:6, f:1, e:3, d:2, c:2; } u;
int
  x[] = { 0,4,8,13,22,32,44,57,72,92,112,134,157,182,210,256 },
  b[] = { 544,9760,13855,9821,9949,10076,10203,13785,13911,14040,14167,14294,10452,10578,10705,10832 };
int main()
{
  int n,i=0,q=0;
  scanf("%d", &n);
  while(i++ <= n) {
    ++u.g;
    if (i > x[q])
      *(int*)&u = b[q++];
  }
#define m(p, q) while (p) putchar(#q[0]);
  m(u.c--, i)
  m(u.d--, s)
  m(u.e++ < 4, d)
  m(--u.e > 4, i)
  m(u.f--, s)
  m(u.g++ < 32, d)
  m(--u.g > 32, i)
  puts("o");
}
```
A fun fact about this code: an earlier version used an array of 256 unions instead of just `u` and `v`. That version caused GCC 4.7.2 to generate an internal compiler error! GCC 4.9 fixed it, however, and the above code works with either version.

# Picat 516 + 2060 = 2576
It is somewhat modified version of [Sergey Dymchenko](https://codegolf.stackexchange.com/users/32308/sergey-dymchenko) program. This version outputs more compact deadfish programs.
```
import planner.
final((N,N))=>true.
action((N,A),B,M,C)?=>B=(N,A+1),M=i,C=1.
action((N,A),B,M,C)?=>A!=16,A<N,B=(N,A*A),M=s,C=1.
action((N,A),B,M,C)?=>A>0,B=(N,A-1),M=d,C=1.
r([X,Y|Z],A)?=>(r([Y|Z],R),A=[X|R];X!=['0'],r([(X++Y)|Z],R),A=R).
r([],A)=>A=[]. r([N],A)=>A=[N]. lf(X)=[X].
table(+,-,min) fs(N,M,L)=>r(map(lf,N.to_string()),X),Np:=0,Pp:=[],
foreach(Y in X)N:=Y.to_integer(),best_plan((N,Np),P),Np:=N,Pp:=Pp++P++[o]
end,L=Pp.length(),M=Pp. main=>foreach(X in 1..255)fs(X,P,L),printf("%s",P) end.
```
As far as I understood "lengths of outputs" sentence, it means that I should sum output without new-line chars. 
Use:
```
picat filename.pi
```
1-255 Codes:
```
picat filename.pi | wc -c    
2060
```

action((N,A),B,M,C)?=>A!=16, A<N, B=(N,A*A), M=s, C=1.
action((N,A),B,M,C)?=>A>0, B=(N,A-1), M=d, C=1.
r([X,Y|Z],A)?=>(r([Y|Z],R),A=[X|R];r([(X++Y)|Z],R),A=R).
r([],A)=>A=[]. r([N],A)=>A=[N]. lf(X)=[X].

foreach(Y in X)N:=Y.to_integer(),best_plan((N,Np),P),Np:=N,Pp:=Pp++P++[o]
end,L=Pp.length(),M=Pp. go=>foreach(X in 1..255)fs(X,P,L),printf("%d %s",X,P),nl end.
main=>time2(go).

# Perl, ~~132~~ 131 bytes + 2036 bytes = 2167
Includes +2 for `-lp`
Run with the target number on STDIN, e.g.
```
perl -lp deadfish.pl <<< 160
```
deadfish.pl:
```
@;=map{s%(o)|(s)|(i|d)|%$_-=e cmp$3.e;$_*=$_-16&&$_ if$2;$1&&$_%eg;@$_=$`;grep/id|di/^y/o//<4,<{o,s,d,i}$`>}~~o,@;until$\="@$_"}{
```
The grep is a filter to constrain the exponential explosion a bit (though this program still needs 2 GB for the hard cases). It also works without but I can't run it on my hardware like that except for the easy cases. But in principle this `110=108+2` byte program works too:
```
@;=map{s%(o)|(s)|(i|d)|%$_-=e cmp$3.e;$_*=$_-16&&$_ if$2;$1&&$_%eg;@$_=$`;<{o,s,d,i}$`>}$a,@;until$\="@$_"}{
```

# JavaScript (E6) 141+3455=3596
Recursive function looking for the closest square root, but avoiding 16 as 16\*16=256 will be changed to 0. Many other answer don't get this point.
```
F=(t,s='o',o='i')=>
  t>3?(
    q=Math.sqrt(t)|0,
    r=q+1,
    q-16?r-16||++r:--q,
    d=t-q*q,e=r*r-t,
    e<=d&&(o='d',d=e,++q),
    F(q,'s'+o.repeat(d)+s)
  ):o.repeat(t)+s
```
**Test** In FireFox/FireBug console
```
for(l=0,i=1;i<256;++i)o=F(i),l+=o.length,console.log(i,o),l
```
*Output*

# Python 3 – 4286 + 168 = 4454
Not a too serious one, but extremely simple. Just finds the best one of adding to 0, a square, a 4th power ~~and an 8th power~~.
**EDIT:** Golfed 75 bytes, the 8th power did nothing
**EDIT 2:** Removed some bytes in order to correctly implement `d`. Score increased, though.
```
i=int(input())
s=round(i**.5)
q=round(s**.5)
o=round(q**.5)
a,b,c,d=i-256if i>127else i,i-s*s,i-q**4,i-o**8
print(sorted([(a*'i'if a>0else'd'*-a)+'o',s*'i'+'s'+(b*'i'if b>0else'd'*-b)+'o',q*'i'+'ss'+(c*'i'if c>0else'd'*-c)+'o',o*'i'+'sss'+(d*'i'if d>0else'd'*-d)+'o'],key=len)[0])
```
# Python 3 – 2594 + 201 = 2795
This one uses a kind of depth-first search to find the shortest program. I added some (unnecessary?) optimizations to it, so I could get the result; this way it doesn't have to run that many paths. Might try to remove some of them. Doesn't beat the JS one as it uses smart tricks like multiple `o`'s.
**EDIT:** Golfed off 93 bytes, I apparently had a crapton of useless code left there by development. Also removed everything I found unnecessary so far. Here I come, JS.
**EDIT 2:** Golfed off another 8 bytes. That `return` was unnecessary.
**EDIT 3:** Golfed an additional 5 bytes. Now that we got rid of that one wo could just put an `elif` instead of the other `return`.
**EDIT 4:** Corrected the functionality of `d`. Size increased by 1 byte, score by some bytes.
```

**APL: 80 + 3456 = 3536**
```
⌽'o',{⍵<4:⍵⍴'i'⋄(b/'ids'),∇(-⊃b)+b[2]+⍵*÷1+3⊃b←(⍵>240)⌽⊃(>,<,=)/|⍵-2*⍨(⌈,⌊)⍵*.5}
```
**Explanation:** (corrected after edc65's note, thanks)
⍵<4:⍵⍴'i' If argument is less than 3, replicate "i" that many times
(⌈,⌊)⍵\*.5 ⍵ is the argument, take square root and take the ceiling and the floor 
|⍵-2\*⍨ elevate those ceiling and floor to power 2, remove argument, and make positive
b←⊃(>,<,=)/ get a boolean vector with a>b, a
(⍵>240)⌽ To avoid going to 256, do "i" for numbers over 240, instead of ^2
b/'ids' use that boolean to take either i, d or s and append it to the solution with ,
,∇(-⊃b)+b[2]+⍵\*÷1+3⊃b Recursively call the function with argument -b[1](http://TryApl.org) +b[2] elevated to the power (inverse of b[3]+1)
*Can count output with:*
```
 +/⊃,/⍴¨(⌽'o',{⍵<4:⍵⍴'i'⋄(b/'ids'),∇(-⊃b)+b[2]+⍵*÷1+3⊃b←(⍵>240)⌽⊃(>,<,=)/|⍵-2*⍨(⌈,⌊)⍵*.5})¨¯1+⍳256
```
¨ applies the function to each number 0-255
+/⊃,/⍴¨ counts total number of elements
Again, you can try all of the above on [TryApl.org](http://TryApl.org)
**BTW:** It's 3456 and not 3455 because I'm considering 0 too, as I think the problem was asking. If It's 1-255 then the score is 80+3455 = 3535
