### My Stupid Str8ts Solver...

I've put the code to my (stupid) Str8ts solver online if anyone is interested in playing with it. Any tweaks / improvements / feedback are extremely welcome.

The code is available on Github at: https://github.com/jamesaustin/str8ts

The solver is able to solve all the Weekly Extreme puzzles (and the user generated puzzles from the feeds) in around 3m on my machine.

The solver runs through a list of rules searching for a hit that allows it to make progress. Changing the order of the rules would change the distribution of rules used whilst solving. The default rules order solves all the puzzles with the following results, where:

Ord - is the order the rule is run in.
Hit % and # - is a count of times the rule was successful.
Digits % and # - is a count of the digits the rule was able to eliminate.

The solver probably relies on searching for chain contradictions more than a skilled solver.

To solve all the puzzles use:
python str8ts.py -i str8ts.txt

To solve a single puzzle and see the steps as they happen (debug it) use:
python str8ts.py -i str8ts.txt weekly187 -d

Happy hacking...
