Metropolis Light Transport

Computer Graphics · Light Transport · 1997 · also: MLT · metropolis-light-transport.yaml

Once a path reaching the light is found, mutate it locally and accept mutations with a Metropolis-Hastings rule, so effort concentrates where transport actually happens instead of restarting blindly.

Colour is the family; a dashed line is the second member of it.
