| void MALSChains::disturb | ( | tChromosomeReal & | sol | ) | [protected] |
Disturb the solution (similar to mutation it uses the disruption_size
Definition at line 256 of file malschains.cc.
| bool MALSChains::hasDiversity | ( | PopulationReal * | pop | ) | [protected] |
Check if there is enough diversity

| unsigned MALSChains::realApply | ( | tChromosomeReal & | sol, | |
| tFitness & | fitness | |||
| ) | [virtual] |
Alter the EA and after the LS, then the EA again, the LS, ...
Implements realea::ProxyEA.

| void MALSChains::setDisruptionSize | ( | double | size | ) |
Set a distorsion size when the solution is a local optimum
- Parameters:
-
size size of maximum disruption
Definition at line 46 of file malschains.cc.
| void MALSChains::setEffortRatio | ( | double | ratio | ) | [virtual] |
- Parameters:
-
ratio. Set the global ratio invested into the Local Search ratio global ls/total ratio (change the intensity, because only one LS improvement is made)
Implements realea::Hybrid.
Definition at line 30 of file malschains.cc.
| void MALSChains::setRestart | ( | RestartStrategy * | restart, | |
| int | maxfailed = -1 | |||
| ) |
Set the restart strategy. If it is not called never it will make a restart.
