Nothing
Consider the intersection of two spaces: the complete solution space to Ax = b and the Nsimplex. The intersection of these two spaces is a nonnegative convex polytope. The package walkr samples from this intersection using two MonteCarlo Markov Chain (MCMC) methods: hitandrun and Dikin walk. walkr also provide tools to examine sample quality. The package implements Dikin walk specified in Sachdeva (2016) <doi:10.1016/j.orl.2016.07.005>.
