We tried to combine 2 or 3 stronge weight by simply “add them together”: We picked up 257aeeb8 (the strongest one by now on http://zero.sjeng.org/ ) and some other weight files which won over 40% to 257aeeb8 in SPRT. We made some “hybrid” weight files by linear superposition——0.5weight1+0.5weight2; 0.25weight1+0.25weight2+0.5*weight3… Surprisingly, we’ve got serval weight files much stronger than 257aeeb8… Here are two of them. Both of these "hybrid" files can win ~70% of the matches to 257aeeb8 (1600playouts).
