Normal mutation

Each point is subject to additive Gaussian noise with probability pm.

doNormalMutation(coords, pm = 0.1, sigma = 0.0025, ...)

Arguments

coords	[matrix] An n times 2 matrix of point coordinates in \([0, 1]^2\).
pm	[numeric(1)] Probability of node mutation. Note that each node is subject to mutation independent of the the nodes. Default is \(0.1\), i.e., in expectation 10% of the points are mutated.
sigma	[numeric(1)] Standard deviation for normal random numbers generator. Default is \(0.0025\).
...	[any] Currently not used.

Value

[matrix] Mutated coordinates.
