Lecture Notes from Foundations of Markov Chain 1.2 Spanning Trees

The aim of this course is to address the complexity of counting and sampling problems from an algorithmic perspective. Typically we will be interested in counting the size of a collection of combinatorial structures of a graph, e.g., the number of spanning trees of a graph. We will soon see that this style of counting problem is intimately related to the sampling problem which asks for a random structure from this collection, e.g., generate a random spanning tree. The course will demonstrate that the class of counting and sampling problems can be addressed in a very cohesive and elegant (at least to my tastes) manner.
