Validator
From PC2wiki
A validator is a program that validates team's output and judge's solutions and judge's data.
To use the PC² auto judge feature a Problem must be defined to use a validator.
Output Validator
An Output Validator judges a submission assigns a judgement.
An Output Validator can be use to validate:
- a team's submission/solution
- judge's solutions
- problem samples
An output validator can be specified in the CDP under
config/<SHORT_NAME>/output_validators/<VALIDATORNAME>/<FILES>
Example:
config/squares/output_validators/sqval/squares_valiator.cpp config/squares/output_validators/sqval/build config/squares/output_validators/sqval/run
- build - a script to build the validator executable
- run - a script to run the validator
run usage
run datafile answerfile feedbackfile [options] < teamsoutput
where
- datafile - judge's input data file
- answerfile - judge's expected output/answer file
- feedbackfile - additional output from the validator, maybe of help to judges
- teamsoutput - team's output
run results/output
- exit code 42 - AC judgement (yes)
- exit code 43 - WA judgement (no, wrong answer)
- (non-42 exit code is either WA or JE (Judging Error)

An output validator can be specified in the CDP under
config/<SHORT_NAME>/input_validators/<VALIDATORNAME>/<FILES>
Example:
config/squares/input_validators/sqval/squares_valiator.cpp config/squares/input_validators/sqval/build config/squares/input_validators/sqval/run
- build - a script to build the validator executable
- run - a script to run the validator
run usage
run feedbackfile < datafile
where
- datafile - judge's input data file
- feedbackfile - additional output from the validator, maybe of help to judges
