solving a scheduling problem with genetic algorithms

I have a scheduling problem. but I don't know how to determine its complexity (NP-hard, NP-complete)? How could we justify the choice of a metaheuristic instead of other for a scheduling problem i.e. ...

How are the lower and upper bound values of the moths determined in the Moth-Flame Optimization algorithm?

I am currently implementing the Moth-Flame Optimization (MFO) Algorithm, based on the paper: Moth-Flame Optimization Algorithm: A Novel Nature-inspired Heuristic Paradigm. To calculate the values of ...

What are most commons methods to measure improvement rate in a meta-heuristic?

When I run a meta-heuristics, like a Genetic Algorithm or a Simulated Annealing, I want to have a termination criterion that stops the algorithms when there is not any significant fitness improvement. ...

Why does Simulated Annealing not take worse solution if the Energy Difference becomes higher?

In Simualated Annealing a worse solution is accepted with this probability: $p=e^{-\frac{E(y)-E(x)}{kT}}$. If that understanding is correct: Why is this probability function used? Because it means ...
