Public Member Functions | |
| InformedStateSampler (const ProblemDefinitionPtr &probDefn, unsigned int maxNumberCalls, const GetCurrentCostFunc &costFunc) | |
| Construct a sampler that only generates states with a heuristic solution estimate that is less than the cost of the current solution using the default informed sampler for the current optimization objective. Requires a function pointer to a method to query the cost of the current solution. | |
| InformedStateSampler (const ProblemDefinitionPtr &probDefn, const GetCurrentCostFunc &costFunc, const InformedSamplerPtr &infSampler) | |
| Construct a sampler that only generates states with a heuristic solution estimate that is less than the cost of the current solution using the provided informed sampler. Requires a function pointer to a method to query the cost of the current solution. | |
| void | sampleUniform (State *statePtr) override |
| Sample uniformly in the subset of the state space whose heuristic solution estimates are less than the current best cost (as defined by the pointer passed at construction). By default just calls sampleUniform(State*, Cost) with cost given by the member variable. | |
| void | sampleUniformNear (State *statePtr, const State *near, double distance) override |
| By default sampleUniformNear throws. This can be overloaded by a specific informed sampler if desired. | |
| void | sampleGaussian (State *statePtr, const State *mean, double stdDev) override |
| By default sampleGaussian throws. This can be overloaded by a specific informed sampler if desired. | |
