When you have many parameters in multiple models with interdependent parameters in feedback cycles the Monte Carlo method lets you sample the space and explore faster. Especially in large scale simulations the execution speed limits exhaustively computing your way through the parameter space. And because there is likely no simple set gradients to follow, I’d suspect the Markov probabilities let you further navigate local maxima and minima more effectively. Something like a breadcrumb trail of past paths through the forest.
