Hello everyone, during October I've been focusing on Cosmic Ray which is a supported package of our Python software stack.

The changes include

All of my work this month was around visit_mutation_site() being able to generate multiple mutations at a single site. For example the code

a < b

can be mutated into:

a <= b
a is not b
a > b
... etc

Previously this was done using different mutation operators but now it is done using a single class and an index to the desired operator replacement. As a follow up other mutation operators had to be updated as well. As a result the code base is cleaner and easier to understand.

I hope you like my work and please subscribe to Mr. Senko if you need faster response cycle for the open source libraries you use.
