GI Software with fewer Data Cache Misses
William B. Langdon, Justyna Petke, Aymeric Blot +1
By their very name caches are often overlooked and yet play a vital role in the performance of modern and indeed future hardware. Using MAGPIE (Machine Automated General Performanc…
A Trillion Genetic Programming Instructions per Second
W. B. Langdon
We summarise how a 3.0 GHz 16 core AVX512 computer can interpret the equivalent of up to on average 1103370000000 GPop/s. Citations to existing publications are given. Implementati…
Failed Disruption Propagation in Integer Genetic Programming
William B. Langdon
We inject a random value into the evaluation of highly evolved deep integer GP trees 9743720 times and find 99.7percent Suggesting crossover and mutation's impact are dissipated an…
A multi-linear geometric estimate
Charlotte Aten, Alex Iosevich
We give a generalization of the geometric estimate used by Hart and the second author in their 2008 work on sums and products in finite fields. Their result concerned level sets of…
Multi-threaded Memory Efficient Crossover in C++ for Generational Genetic Programming
W. B. Langdon
C++ code snippets from a multi-core parallel memory-efficient crossover for genetic programming are given. They may be adapted for separate generation evolutionary algorithms where…
Genetic Improvement @ ICSE 2020
William B. Langdon, Westley Weimer, Justyna Petke +13
Following Prof. Mark Harman of Facebook's keynote and formal presentations (which are recorded in the proceedings) there was a wide ranging discussion at the eighth international G…
