And one more question.
I want to make a task with the masterjudge: "1001. Score is % of correctly solved sets".
So I chose this masterjudge, changed "assessment type" to "maximize score".
The task works corractly but all users which get AC get maximum points for the task even if they have 0/100 pts.
How to fix this?
I have to write my own judge also?
Based on the information in this thread, I've written a generic custom judge in Python that tests the correctness of submitted Python source code for a particular problem based on the evaluation of a doctest (read from the problem's input). The judge works as intended, except for the following two cases:
Judge != Master Judge
You should allow only TEXT submissions (to prevent of execution)
Set 'Problem type' to 'interactive' (more results)
Judge's TLE == IE
For classic problems judge's time limit is const and == 150s, for interactive problems judge's time limit is 2 * solution's time limit + 2s. You can use getrlimit() to determine it.
What information becomes available for what kind of judge indeed wasn't clear for me while writing early prototypes of my judge. My questions were specifically related to judges, not master judges. I had to find out the use of the exit status for judges by trial-and-error. I never found any documentation about that. Up until now it is still unclear to me how to generate a "run-time errors" status from judges. My judge is able to detect run-time errors, but I've found no way to set this status using an appropriate exit status.
My Python-specific judge (using doctests) doesn't suffer from the fact that SPOJ does run the user code. It simply ignores the outcome of that process. My problem with allowing only TEXT submissions (which would prevent an extra execution of the code) is that users (in my case students that are new to programming) submit Python code. Having them submit their code as TEXT would be quite confusing.
One particular reason I've written a generic Python-specific, is to perform tests on source code beyond a test purely based on input/output. It also allows mixing source code submitted by the user with additional source code. For example a skeleton of classes users have to further implement or code that adds extra layers to the source code submitted by the user, e.g. to provide additional feedback or add a graphical layer to it. In my opinion, the design decision to automatically execute the source code provided by the user is to tightly linked with the idea of testing the "correctness" of submitted source code, based only on the output the software generates for a given input. A more flexible solution would use "lazy execution". With that, I mean that the source code of the user is only executed in case the judge requests the output generated by the source code. This would mean that if the judge ignores the output, the code is never executed beyond the control of the judge.
Explain "more results". As far as I understood the principle behind interactive problems, it means that the judge can respond interactively to output generated by the program submitted by the user. This output on it's turn then can be used by the user program. For the moment, I think I don't need this feature, unless I've got it wrong.
This I figured out. However, I would like my Python-specific judge to take into account the time limit that is specified in the problem definition. In order to do that, the judge should be able to access that time limit (e.g. through an environment variable).
The getrlimit() function actually is the answer to my question addressed in point number 4. I can also get the information coming from that system call in Python.
Judge: problem_input, problem_output, tested_output, tested_src.
Master Judge: results of testcases, tested_src.
// spoj.h

#define SPOJ_RV_MLE 6
#define SPOJ_RV_EOF 7
#define SPOJ_RV_IE 255In each testcase judge is executed only if there was no problem with tested (RE/TLE/MLE).
Thanks for the explanation about the extended list of exit statuses when using an interactive job. This indeed helped me out in properly reporting run-time errors in my generic Python judge based on doctests. However (detail): I don't understand the design decision for the SPOJ backend to make a distinction between the supported exit status list for regular judges and interactive judges.
This indeed provides the time limit as I need it. Thanks.

Just to make sure, spoj_p_info, file descriptor 6, is only available to problemsetters and spoj_u_info, file descriptor 7, is available to both users and problemsetters? Note that in the spoj.c example the descriptions are the other way around, but judging on the names I would assume that the one in spoj.h is the correct one.
HI
I uploaded 2 test cases and for 'RAONE'
after that i uploaded 1 more test case .. When i rejudge only the first 2 test cases were getting judged .. why not the new one ?
Maybe your post is so old that it's useless to respond, but it seems you forgot to check the box for "Refresh cached info about test sequence" above the "Start rejudge" button.
Just for your information here is my judge for PELL4C5.
#include "spoj.h"
#include <stdlib.h>
using namespace std;
#define SEUIL 45
// SEUIL is the minimum number of line to output to get AC.
/*
* This a variation around the judge 'ignore whitespace',
* for the problem PELL4C.
* So you can use every whitespace separator
*/
// <0-255> normal, - 1 white, -2 eof
int getChar(FILE *f, bool ignWhite) {
bool white;
int ch;
do {
if ((ch = getc(f))==EOF)
return -2;
if (ch==' ' || ch=='\n' || ch=='\t' || ch=='\r')
white=true;
else white=false;
} while (ignWhite && white);
if (white)
return -1;
return ch;
}
void myexit(int score) {
score>>=1; // now 1p per lines
if (score<SEUIL)
exit(SPOJ_RV_NEGATIVE);
fprintf(spoj_score, "%d\n", score );
exit(SPOJ_RV_POSITIVE);
}
int main(void) {
int score=0;
spoj_init();
bool ignWhite = true;
int ch1 = getChar(spoj_t_out, ignWhite);
int ch2 = getChar(spoj_p_out, ignWhite);
while (ch1 == ch2) {
if (ch1==-2) {
if (!ignWhite)
++score;
myexit(score);
}
if (ch1==-1){
ignWhite =true; ++score; // 2p per lines
} else
ignWhite=false;
ch1 = getChar(spoj_t_out, ignWhite);
ch2 = getChar(spoj_p_out, ignWhite);
};
if (ch1 == -2){
/*
* we're taking care of several cases for last line output
* "10 19 " -> 1 more point
* "10 19" -> 1 more point
* "10 " -> 0 point
* "10" -> 0 point
*/
if (!ignWhite)
++score;
myexit(score);
}
if (ch2 == -2 && ch1 == -1 && getChar(spoj_t_out, true)==-2)
myexit(++score);
return SPOJ_RV_NEGATIVE;
}For your information, here's a fac simile of my judge for TIP3.
#include "spoj_interactive.h"
#include <time.h>
#define Q 2
// or another one
int main(){
spoj_init();
// always at the beginning
srand ( time(NULL) + 123456789 );
// or another number...
int secret;
secret = rand()%Q;
const char *entree[Q] = {"222", "2222"};
// or some other input strings, my own input ones ;-)
const char *sortie[Q] = {"21", "291"};
// and corresponding awaited answer
char answer[32];
spoj_printf("%s\n", entree[secret]);
// using macro to print data for tested
// in case tested ended -> EOF
spoj_scanf("%s", answer);
// using macro to get data from tested
// in case of wrong data -> WA
// in case tested ended -> EOF
fprintf(spoj_p_info, "%s\n", entree[secret]);
fprintf(spoj_p_info, "%s\n", sortie[secret]);
fprintf(spoj_p_info, "%s\n", answer);
// outputting information that is only available for ps
for(int i=-1;sortie[secret][++i];)
spoj_assert(sortie[secret][i]==answer[i]);
// condition unfulfilled -> WA
return SPOJ_RV_AC;
// AC
}Feel free to send by PM suggestions to improve it, I'm a noob in C++.
When you update the test files and you want to rejudge
CHECK the flag
"Refresh cached info about test sequence"
(just a little hint to avoid headache when doing a rejudge becaude of you weak testcases files)

I've sent in an application weeks ago and haven't received a reply.
Is this normal, does this mean the application was not accepted?
Thanks in advance.
