AVIJIT BASAK updated MATH-1637:
-------------------------------
Description:
{*}Improvement of BinaryChromosome data structure{*}: Currently binary
chromosome has been implemented as a list of Integer data where each binary bit
is represent as Integer. This reduces the memory utilization to a considerable
extent as 31 out of 32 bits are wasted. This needs to be implemented as an
array of long data type with each long data element representing 64 binary
alleles following the article "https://arxiv.org/abs/2103.04751";. This would
improve the memory utilization close to 100%. This will also impact the
corresponding mutation and crossover operations.
Removed Components: none
New Components: OnePointBinaryCrossover
Affected Components: BinaryChromosome, BinaryMutation
