in reply to Re^11: Travelling problem (Anyone better 86850?)
in thread Travelling problem

Here's my second attempt at a threaded version. Running it with -T=24 won't be fastest unless you have 24 cores, but it has the interesting side effect of running all first picks in parallel.

Ignore this! (I was forgetting to add the last distance :( )which yields several better than 84860 scores in just a few minutes:
