GZigZag Benchmarking module This module contains various pieces of code that test relative speeds of various operations. The point is 1) provide a good basic intuition of what is fast and slow in Java, for purpose of choosing implementation methods 2) provide a test for different JVM's efficiency on different tasks (there are surprising diffrences here) 3) provide a testbed for zigzag algorithms and possible extensions, such as the constraint model where the feasibility from a speed perspective can be studied without building the whole system.
