ell::SAC_NoMinimaChange Class Reference
#include <SamplingAbortionCriterion.hh>
Inheritance diagram for ell::SAC_NoMinimaChange:
Detailed Description
This criterion is used to decide if a sampling process changing a landscape topology should end based on the number of minima of the landscape. If this number does not change for given number of iterations abortSampling gives true.

Member Function Documentation
| bool ell::SAC_NoMinimaChange::abortSampling | ( | const LandscapeTopology *const | lt, | |
| const bool | ltChanged = true | |||
| ) | [virtual] |
Decides whether or not the sampling should be aborted or has to be continued based on the number of minima of the topology. If this number has not changed for MAX_NO_CHANGE_ITERATIONS successive iterations the function returns true.
- Parameters:
-
lt the landscape topology that is used to decide if the sampling should be aborted or not based on its properties ltChanged whether or not the landscape was changed since the last call of this function
- Returns:
- true if the sampling should be aborted, false otherwise

| void ell::SAC_NoMinimaChange::reset | ( | void | ) | [virtual] |
Resets the internal counter of the number of iterations seen so far where no change in the number of minima was visible.
