Webto-register moves with register coalescing. Algorithms for register coalescing are usually tightly integrated with register allocation. In contrast, Pereira and Palsberg describe a relatively straightforward method that is performed entirely after graph coloring called greedy coalescing. Greedy coalescing is based on two simple observations: WebGreedy algorithms { Overview I Algorithms for solving (optimization) problems typically go through a sequence of steps, with a set of choices at each step.

Thus the quality of your solution is at least as great as that of any other solution. In particular, it is at least as great as an optimal solution, and thus, your algorithm does in fact return an optimal solution. Main Steps

Weboptimal solution. The algorithm’s approximation ratio is then given by . If we are dealing with a maximization problem, we expect <1. Similarly, we would expect >1 for a minimization problem. In these notes, we will provide an overview of iconic techniques used in the design of approximation algorithms by looking at an example problem: Set Cover.
