mlemanczyk a6d408f2aa Predictive scanning implemented for bydivisor method. 2026-01-03 20:01:22 +01:00
mlemanczyk 9a6a1968b7 Merge branch 'simplify-bydivisor' of https://github.com/mlemanczyk/even-perfect-numbers-scanner into simplify-bydivisor 2025-12-28 00:59:18 +01:00
mlemanczyk 87a66e4eca DivisorSet scans added as EnumDependentTemplate to MersenneNumberDivisorByDivisorCpuTesterWithTemplate. New Pow2Groups scan implemented based on statistics for high divisors. MersenneNumberDivisorByDivisorPrimeScan sessions integrated into MersenneNumberDivisorByDivisorPrimeScanSessionWithTemplate. Various micro optimizations to eliminate variable, unnecessary struct creations and continue scans in higher divisor ranges, when lower ranges are exhausted. --bydivisor-k-increment command-line argument added. 2025-12-28 00:45:08 +01:00
