Subject: Code for restarting optimization welcome.
Dear JGAP Users,

>From a rusty C programmer, new to Java, to RePast, and to JGAP:

I want to restart an optimization after halting and writing out the
latest population of chromosomes.  Before restarting, I'd like to
seed the last population with some designer chromosomes.

Questions: 1. How to write out each generation of chromosomes?
2.  How to read in a particular population at the beginning of any
optimization run?

Any code welcome or pointers welcome.

Bob Marks

Robert,

Please see the sample class MinimizingMakeChange in package examples: There,
evolution takes place within a loop (look out for population.evolve()).
After evolve(), you can get the population by population.getChromosomes()
and set it back via population.setChromosomes() . Please see class
org.jgap.Population .

Best
