On the role of randomness in exact tree search methods
High-sensitivity to initial conditions is generally viewed as a drawback of tree search methods, as it leads to an erratic behavior to be mitigated somehow. In this talk we address the opposite viewpoint. Our working hypothesis is that erraticism is just a consequence of the exponential nature of tree search, that acts as a chaotic amplifier, so it is largely unavoidable. We discuss possible ways to actually take advantage of randomness, and present computational experiments on a testbed of difficult MILP instances.
