Unexpected behavior when running with constraints

[AniekMarkus]

Rerunning mix_4.project, rule length=3 with constraint balancedAccuracy=0.5:

• usually same B_ACC: 62.28 - same as unconstraint, occasionally no rule found B_ACC: 0
• total count candidates including constraint: differs across runs
• happens for both parallel=no and parallel=yes (parallelmethod=ONE or TWO)

[AniekMarkus]

Does not occur for other types of constraints?

Accuracy=0.7:
Total Count Cutoff Sets:2194
Total Count Candidates (incl constraints):705

Specificity=0.8
Total Count Cutoff Sets:2194
Total Count Candidates (incl constraints):630

With balanced accuracy constraint on Mac:

expression failed to parse:
error: <user expression 0>:1:1: use of undeclared identifier 'CurrentCondition'
CurrentCondition->NextSame
^

(problem does not occur in Linux)

[AniekMarkus]

OutputMethod=EVERY -> all candidate rules
OutputMethod=INCREMENT -> found new candidates rules
OutputMethod=BEST-> final best candidates rule
-> Printing does work in parallel (with constraints)

PrintCutoffSets=yes -> all generated rules
-> Printing does not work in parallel

Output C++
Balanced Accuracy >= 0.6 (min and max length = 3)

Best length: 3
Best candidate: '198124209' = "TRUE" OR '316139209' = "TRUE" OR '316139210' = "TRUE"
