Add getLastRunBestChromosome() and release 0.3.0#3
Merged
Conversation
Expose the historical best solution of a run, which survives shake/reset, unlike getBestChromosome() (the current-population best that a later shake/reset may drop). - native: brkga_get_last_status_best_chromosome copies last_status.best_chromosome (the incumbent run() snapshots on every improvement), with bounds check + guard. - Java: BrkgaMpIpr.getLastRunBestChromosome() mirrors the getBestChromosome pattern via a new NativeBrkga handle; its fitness equals the AlgorithmStatus bestFitness that run() returns. Clarify getBestChromosome's javadoc to point here. - test: LastRunBestChromosomeTest covers throw-before-run, survival across forced shake/reset, and fitness matching the run's bestFitness. - Bump 0.2.0 -> 0.3.0 across POMs, examples brkga.version, README/GUIDE/JAVA_GUIDE dependency snippets and the native build script; add a README upgrade note that custom native libs must be rebuilt from 0.3.0 for the new symbol.

What
Adds
getLastRunBestChromosome()— the historical best solution of a run, whichsurvives
shake/reset, unlikegetBestChromosome()(the current-population bestthat a later shake/reset may drop). Bumps the version to 0.3.0 for release.
Changes
brkga_bridge.cpp): newbrkga_get_last_status_best_chromosome, copyinglast_status.best_chromosome(the incumbentrun()snapshots on every improvement),with bounds check + exception guard.
BrkgaMpIpr,NativeBrkga): newgetLastRunBestChromosome()mirroring thegetBestChromosomepattern; its fitness equals theAlgorithmStatus.bestFitnessthatrun()returns. ClarifiesgetBestChromosome's javadoc to point here.LastRunBestChromosomeTest): throw-before-run, survival across forcedshake/reset, and fitness matching the run's
bestFitness.brkga.version,README/GUIDE/JAVA_GUIDE dependency snippets and the native build script; README upgrade
note that custom native libs must be rebuilt from 0.3.0 for the new symbol.
Notes
The native
.sois recompiled from source at build time, so the new symbol ships in thepublished artifact. Local build here is blocked by an ancient system g++ (9.4, no
<concepts>); CI (modern g++) is the authoritative build.
