version 1.5 had some bugs, causing it to hang in some positions towards the end of the game. For that reason I hurried this release as much as I could. Root move selection, aspiration window handling and root search are all significantly altered, and hash reuse logic has been improved. Strength was not a primary concern, but I was pleased to see that score against previous version exceeded 57%.

Re: Rodent 1.6 released
PK wrote:version 1.5 had some bugs, causing it to hang in some positions towards the end of the game. For that reason I hurried this release as much as I could. Root move selection, aspiration window handling and root search are all significantly altered, and hash reuse logic has been improved. Strength was not a primary concern, but I was pleased to see that score against previous version exceeded 57%.
I thought it was just my computer doing it. Happy to see this.

Re: Rodent 1.6 released
@Werner: it looks like a perfect stress test: both immediately forced draw (a situation where v. 1.5 used to get it wrong) and last move before time time control. Have You - or anybody for that matter - seen similar error of v. 1.6 not on a move preceeding time control?

now played 100 games - I had one more crash - too in a totally draw postition (4men) before move 160... So no problem to correct the result.
Wolfgang will make more games for 40/4 list - I ask him to watch the results too.
best wishes

Re: Rodent 1.6 released
OK, so now I know that my recent fixes fail at the last move of repreating time control in a drawn position. This should be enough data to do something about that. Thank You for Your report again!
