◆ sampleGaussian()

overridevirtual 
Sample a state using a Gaussian distribution with given mean and standard deviation (stdDev).
As with sampleUniform, the implementation of sampleGaussian is specific to the derived class and few assumptions can be made about the distance between state
and mean
.
Implements ompl::base::StateSampler.
Definition at line 56 of file DiscreteStateSpace.cpp.
◆ sampleUniformNear()

overridevirtual 
Sample a state near another, within a neighborhood controlled by a distance parameter.
Typically, StateSamplerderived classes will return in state
a state that is uniformly distributed within a ball with radius distance
defined by the distance function from the corresponding state space. However, this is not guaranteed. For example, the default state sampler for the RealVectorStateSpace returns samples uniformly distributed using L_inf distance, while the default distance function is L_2 distance.
