Nice to have it that fast after the contest, well done 
Also FYI looks like its leaderboard is missing in the optim category of the leaderboard dropdown.

How to get my score given the referee and my player (to try models locally)? I cloned the repository but I don’t find how to simply get my score on each test cases without the graphical interface (on localhost:9999)? Got sample code (in java)?
Thanks. 
try replacing gameRunner.start() with gameRunner.simulate() in the Main. It won’t launch the interface and there will be a score in the return of the function in a map called “metadata”

It worked!! Thank you _CG_jupoulton.
In the class com.codingame.gameengine.runner.dto.GameResult.Main I replaced the code
gameRunner.start(9999);
by
GameResult gameResult = gameRunner.simulate();
System.out.println( gameResult.metadata );
and I get {“Points”:“65”} in the console
That’s what I did during the contest, allows you to run all tests at once: Github.
You can also run a test multiple times with an average score if you want.
I changed two other files as well, you may want to clone the whole repo.

Yes eulerscheZahl it runs OK, but it needs to set the input in that json pattern. For example:
{
“title”: {
“1”: “Divisé”,
“2”: “Split”
},
“testIn”: “#R…l…D#\n#…r…#\n#…l…#\n#…r…#\n#dudududu#udududud#\n#…r…#\n#…l…#\n#…r…#\n#U…l…L#\n###################”,
“isTest”: “true”,
“isValidator”: “true”
}
Is there a way to run the simulation directly with what we get as game input? For example like
#########.#########
#########D#########
#########.#########
#########.#########
…R…R…
#########.#########
#########.#########
#########D#########
#########.#########
#########.#########
1
10 4 R
And get the result score…
Thanks.
I don’t see the problem with the json format: the referee loads the json file and converts it to the format expected by your bot.
The only problem I can imagine is when you want to create your own testcases.
@ eulerscheZahl It needs to convert from what I get as input to the JSON: arrows to lower case and robots to their position and orientation in upper case (no problems if I want to create my own test case knowing thoses rules)… This is just one more step! I’d like to use the referee as I play one CodinGame : I put the inputGame in my code given my player and I get the score… just simply, without to have to implement a kind of “middleware” between the CodinGame given code and what I have to submit.
Is there an error with the Results - Details page, it says every Validator passes successfully (green), even if there is an error or timeout?
That’s a feature added for the contest: imagine you fail one test in the rerun and suddenly rank below 1000 with a strong code. Passing everything ensures that you will only be sorted by score, not the the number of passed validators.

Validators 17 (Cells) and 28 (The Best Way) are always invalid!!!
Tried my old solution from Oct. 18 and a dummy solution (code writes just newline)
and get only 93% instead of 100%.
All test cases work fine!
Any ideas?

Thank you for reporting the issue. Should be working now.
yep, thx!!!
insignificant comment, but there’s a typo:
“1 character direction, the direction if faces (U, R, D or L).”
should probably be “it”

The default code in C doesn’t read input correctly, the size of line should be 21 instead of 20.
In Java, is it normal than just parsing inputs takes around 2s…
I tried two technique, the usual one with Scanner and an other one with DataInputStream to speed up the process. Both take around 2s.
When parsing I create 10*19 + $nb_of_robots objects and two boolean arrays, that’s not that big.
I tried to profile the code with VisualVM on my machine and could not find any bottleneck on this method.
edit:
I found the 2s with the following method:
long start = System.nanoTime();
readInputs();
System.err.println("after read " + (System.nanoTime() - start));
Which result to “after read 1890680780” = ~2s
readInputs method:
Scanner sc = new Scanner(System.in);
int platformCount = 0;
for (int i = 0; i < 10; i++) {
String[] line = sc.nextLine().split("");
for (int j = 0; j < line.length; j++) {
CellType cellType = CellType.valueOfLabel(line[j].charAt(0));
int id;
if (cellType.canBeModified()) {
id = platformCount * 4;
platformCount++;
} else {
id = -1;
}
intialMap[i][j] = new Node(id, j, i, cellType);
}
}
int robotCount = sc.nextInt();
robots = new Robot[robotCount];
neverMutatedRobots = new Robot[robotCount];
robotsStatus = new boolean[robotCount];
aliveRobotsCount = robotCount;
boolean[] historic = new boolean[platformCount * 4];
for (int i = 0; i < robotCount; i++) {
int x = sc.nextInt();
int y = sc.nextInt();
String direction = sc.nextLine();
CellType cellType = CellType.valueOfLabel(direction.charAt(0));
robots[i] = new Robot(x, y, cellType, historic);
neverMutatedRobots[i] = new Robot(x, y, cellType, historic);
robotsStatus[i] = true;
}
I saw you did a good score in Java, may I ask if you have the same issue?
@wala @LaurentTrk @Redstrike
Quick question, are you profiling your parsing on the first turn? Do you get similar results if you profile a later turn?
In this game there is only one turn (if I understood correctly).
You basically read inputs then do some computation to output the map configuration you want.
