I am not very sure but multiplying by 20000 can bias the initial population to have very high numbers to begin with and bias/limit our search space.

We need to test the influence with and without of this constant on the objective function. Todo when we solved the constraint part.

Ran a small simulation with only 50 generations with & without the 20k

Without 20k, objective cost: 492117
With 20k, objective cost: 429969

It is a significant difference, coming from the transportation.

--> We should later run more tests with more generations/population
