What are the strongest settings for HIARCS 13 UCI?
The default settings are believed to be the strongest although it is very true to say we did not have time to test all the settings to be absolutely sure. The changes from default settings which are most likely to have the potential to be stronger than HIARCS 13 UCI default are • Higher selectivity settings than 4 may offer improved performance. Currently results on this are inconclusive. • Some testers think Optimistic Search is better OFF at longer time controls but we have insufficient data to be sure either way. • The other setting worth experimentation is the Combinations OFF setting as extra work has been done in HIARCS 13 on this. • Against most programs that are weaker using the Hiarcs Draw value (anti-contempt factor) can give even better results. The value of this Hiarcs Draw value tells HIARCS to either prefer draws (positive values) or avoid them (negative values). Against weaker programs a Hiarcs Draw Value of -15 can be quite effective.
