Observe that in the small progress measures algorithm the choice of the next vertex that is considered for lifting is non-deterministic. For this assignment you must consider a number of dierentlifting strategies and implement these. 1. Implement the small progress measures algorithm for solving parity games. Ensure that your implementation: (a) can read parity games in the PGSolver format;1 (b) treats the parity games as min parity games, i.e. implements the small progress measures algorithm as described in the lecture (note: all tools in the PGSolver toolkit generate and use max-parity games, whereas you are required to use and solve min-parity games). (c) implements at least the following two lifting strategies: Input order lift the vertices in the parity game in the order they appear in the input (vertices are represented by numbers in the PGSolver format); i.e. if the input contains vertices 0; : : : ; 10, start with lifting 0, then 1, up to 10, then restart at 0 again, until the measures stabilise. Random order lift the vertices in the parity game in randomised order, i.e. x a ran- dom order before starting starting your algorithm, and than iteratively lift vertices in this order, until the measures stabilise. Include the code of the algorithms in an appendix (le reading and other auxiliaries may be omitted from the appendix), and include all relevant source les when you send in your report. Make sure your code compiles/can be executed on Linux or Mac OS X (e.g. include .jar les for Java).
