Lab4 Gale-Shapley and Irving Algorithms

Galey-Shapley and Irving Algorithms (Groups of up to 3 students)

1. Find the best and worst cases for the Gale-Shapley and Irving ( An Efficient Algorithm for the “Stable Roommates” Problem) Algorithms and run in Colab these algorithms for those cases for n=4 and 40.

2. Run the Gale-Shapley Algorithm 100 times using random permutations as preference lists for n=4 and 40. Find the minimum, maximum and average number of iterations and plot the distribution of the number of iterations.
3. Simulate the the Gale-Shapley and Irving algorithms using random preference lists , for n=4 and 40 and generate a gift animation fo the type show in "Illustrating the Deferred Acceptance Algorithm with R – Code https://www.r-bloggers.com/illustrating-the-deferred-acceptance-algorithm-with-r/
