|
||||
The \fBpeoSyncMultiStart\fP class provides the basis for implementing the synchronous multi-start model, for launching several solution-based algorithms in parallel on a specified initial population.
|
||||
|
||||
As a simple example, several hill climbing algorithms may be synchronously launched on the specified population, each algorithm acting upon one individual only, the final result being integrated back in the population. A \fBpeoSyncMultiStart\fP object can be specified as checkpoint object for a classic ParadisEO evolutionary algorithm thus allowing for simple hybridization schemes which combine the evolutionary approach with a local search approach, for example, executed at the end of each generation.
