<ul><li>The CSES problem set, created by Antti Laaksonen and other developers, is a valuable resource for programming practice.</li><li>The problem 'Elevator Rides' involves finding the optimal number of rides and weight of the last trip in a permutation.</li><li>A dynamic programming approach can be used to solve the problem by defining a state with parameters related to the optimal permutation.</li><li>The time complexity of the solution depends on the iteration over subsets of the set, similar to knapsack problems.</li></ul>
