Hello,
Let us suppose that I have two metaheuristics (Alg1, Alg2) and I have to share the population between them and, in addition, to switch the execution of both algorithms per generation of a ne…

### Motivation
This is part of #2974
The Optuna's tests have many stub objective functions. We can reduce coding cost to write tests by organizing them.
### Description
By gathering the stub ob…
