--------------------------------------
Hi Gilles, thank you for clarification, sounds good. Sent an e-mail to "dev" ML.
> Infinite loop for CycleCrossover with duplicates
> ------------------------------------------------
>
> Key: MATH-1451
> URL: https://issues.apache.org/jira/browse/MATH-1451
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.6.1
> Environment: Home PC
> Reporter: Gabriele Rossi
> Priority: Major
> Attachments: test-apache-math3.zip
>
>
> I've found an infinite loop when recombining two integers Chromosomes
> admitting duplicates with CycleCrossover class.
> For example, recombining example Chromosomes it works fine, but, if you
> substitute all "8" with "7", you run into an infinite loop while mating.
> I attach the self-contained unit test (JUnit) for a better comprehension
> (issue a mvn clean install to run).
> I added a little quick patch to fix, which I'm happy to provide, even could
> be less efficient than original.
