Small Progress Measures is one of the most efficient parity game solving algorithms. The original algorithm provides the full solution (winning regions and strategies) in $O(dm \cdot (n/ \lceil d/2 \rceil)^{\lceil d/2 \rceil} )$ time, and requires a re-run of the algorithm on one of the winning regions. We provide a novel operational interpretation of progress measures, and modify the algorithm so that it derives the winning strategies for both players in one pass. This reduces the upper bound…

Improvement in Small Progress Measures
TLDR
The algorithm is modified so that it derives the winning strategy for both players in one pass, which reduces the upper bound on strategy derivation for SPM to O(dm.(n/floor(d/2))^floor( d/2)).

Small Progress Measures for Solving Parity Games
TLDR
A new algorithm for deciding the winner in parity games, and hence also for the modal µ-calculus model checking, based on a notion of game progress measures, characterized as pre-fixed points of certain monotone operators on a complete lattice.

TLDR
The aim of this chapter is to review some of the algorithmic approaches to the problem of computing winning strategies in parity games with finite arenas and other two-player games, and to underline the importance of looking for an efficient algorithm solving this particular problem.
An Optimal Strategy Improvement Algorithm for Solving Parity and Payoff Games
TLDR
A novel strategy improvement algorithm for parity and payoff games is presented, which is guaranteed to select, in each improvement step, an optimal combination of local strategy modifications.
Non-oblivious Strategy Improvement
TLDR
A structural property of these games is described, and it is shown that these structures can affect the behaviour of strategy improvement and can be used to accelerate strategy improvement algorithms.
Zielonka's Recursive Algorithm: dull, weak and solitaire games and tighter bounds
TLDR
It is shown that an optimisation of Zielonka's algorithm permits solving games from all three classes in polynomial time, and that there is a family of (non-special) games M that permits the algorithm to establish a lower bound of 2^(n/3), improving on the previous lower bound for the algorithm.
Solving Parity Games in Practice
TLDR
A generic solver is presented that intertwines optimisations with any of the existing parity game algorithms which is only called on parts of a game that cannot be solved faster by simpler methods, showing that using this approach vastly speeds up the solving process.
