We present an algorithm which in n3 (log n)3 time constructs a 3-regular expander graph on n vertices. In each step we substitute a pair of edges of the graph by a new pair of edges so that the total number of cycles of length s=⌊clog n⌋ decreases (for some fixed absolute constant c). When we reach a local minimum in the number of cycles of length s the graph is an expander. © 1994 Akadémiai Kiadó.
