I use your algorithm to achieve a mining program，but could not pass the check of zcashd. Would you please point out the difference between your algorithm and the official one? Thank you in advance.

My code is already year old, while official one is evolved, so by now it could be more optimized than mine. basicSolver.c is C port of official algo of year ago, while basicSolver-opt.c is optimized version of that version. You could diff -u basicSolver.c basicSolver-opt.c to see the difference. Basically, indices intersection filter is optimized by using sorted arrays instead of O(N^2) loop.
