Subject: | [Bug-gnubg] Bug in bearoffdump? |
Date: | Tue, 27 Dec 2016 18:47:48 +0000 |
I tested out bearoffdump on a test database using normal distribution format and got the following strange output (running on a 64bit Debian system). I was expecting a similar format to a non-ND database and wonder if this is a bug:
$ bearoffdump -n 56 ntest_osx2.bd
Bearoff database: ntest_osx2.bd
Position number : 56
Information about database:
* On disk 1-sided bearoff database evaluator
- generated by GNU Backgammon
- up to 15 chequers on 2 points (136 positions) per player
- distributions are approximated with a normal distribution
- database includes gammon distributions
