Generation stops for genetic evolution with initial population

Hello,

When I'm running genetic evolution with initial population, strategy generation stops almost instantly.
Here is an error I found in logs.
Plus see attached config and initial population

Actually looks like same error ( Comparison method violates its general contract!) happens with any type of genetic evolution. Could some one  look at this? This is CRITICAL

Status changed from New to Fixed

Initial population problem is fixed.


As for error "Comparison method violates its general contract!" - do youy experience it regularly? I have never seen it and as I checked the code I don't know how it could have happened.


If you see it often, can you create a new task for it and attach your build config? I'm closing this task.

Hi Mark,

Yes, I getting this error constantly. Opened another ticket: https://roadmap.strategyquant.com/tasks/sq4_3478
