Build options are officially allowed on C++ challenges. Our rules never covered this, and that's our mistake. The default build is C++23 with -O2 -march=native, and you may tune it from inside solution/: compile options and LTO via solution/libraries.cmake, and pragmas in your own sources. The benchmark and scoring stay fixed. Exploratory research is always welcome. Read the rules
