Tests for multi-objectives fail

[jbytecode]

After performing

(Metaheuristics) pkg>  test

I get

Multi objective: Test Failed at /Users/istar1/Desktop/code/julia/Metaheuristics.jl/test/multi-objective.jl:47
  Expression: Metaheuristics.PerformanceIndicators.igd(result.population, pf) <= 0.2
   Evaluated: 0.22673908824247319 <= 0.2
Stacktrace:

Is 0.2267 reasonable or the right result? How about changing the threshold or using a RNG to generate an exact solution in each time?

Thanks.

Using a RNG is the best option (suggested by #24); however, a lot of work is required due to we need to update every rand(...) by rand(rng, ...).

Changing the threshold (say 0.5) is OK for me.

I am going to send a PR for this.

I think this PR solves it and I have all of the tests passed in my machine.

Solved.
