6/52<strong>Fast</strong> <strong>Exponential</strong>-<strong>Time</strong> <strong>Algorithms</strong>Iterative CompressionBasic ApproachFor i = 1, 2, . . . , n, compute α(G i ) and a maximum independentset B i of G i . Thus B n is a maximum independent set of G n = G.Compression (Expansion) : Given a maximum independent set B iof G i , compute a maximum independent set of G i+1 = G i + v i+1 .How are we making use of the maximum independent set B i ?
