Release Notes 1.81

August 7, 2012

 

Fixing an old scaling problem that was known but neglected because of laziness (I can afford that

luxury) and lack of an easy solution. With increasing time controls Rebel 12, ProDeo tended to

lose more and more strength in comparison with other engines.

 

Oddly a program that was known in the past to perform better at longer time controls than at

blitz has gone completely the opposite way. The price one has to pay for doing nothing. Version

1.81 is meant to turn that tide and its test results look good.

Based on these results one might expect this upwards pattern to continue at longer time controls.
