Markov Chain Monte Carlo (MCMC) Simulation with Metropolis Algorithm
Introduction
This is an implementation of the MCMC simulation with Metropolis algorithm example from the Statistical Rethinking [1] book (chapter 9.1 page 265) in Go.
King Markov wants to visit every 10 islands of his kingdom regularly. He wants to visit islands were with a bigger population and therefore with more people who love him more often than smaller islands. The second island is twice as popular as the first, the third is three times as popular as the first, and so on. Using MCMC allows the king to visit the islands depending on the popularity without scheduling every trip in advance.

Run Simulation
go run ./main.go creates a barchart.png as shown in the result section.
You can change the vars numWeeks and numIslands to adjust the simulation. But plotting is only possible for 10 islands.
Results
This is the resulting bar chart after 100000 (1e5) weeks.
