You've got the same kind of problems for optimisation, where you look
for an absolute minimum and not a local one.

A popular solution is to make a Monte Carlo method on the starting
points, e.g. with the Metropolis-Hastings algorithm

So maybe you can try this to find all the possible solutions?

Hope this helps
