BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-84-1003 ENTRY:: May 29, 1995 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Parallelism and greedy algorithms TYPE:: Technical Report AUTHOR:: Anderson, Richard AUTHOR:: Mayr, Ernst DATE:: April 1984 PAGES:: 18 ABSTRACT:: A number of greedy algorithms are examined and are shown to be probably inherently sequential. Greedy algorithms are presented for finding a maximal path, for finding a maximal set of disjoint paths in a layered dag, and for finding the largest induced subgraph of a graph that has all vertices of degree at least k. It is shown that for all of these algorithms, the problem of determining if a given node is in the solution set of the algorithm is P-complete. This means that it is unlikely that these sequential algorithms can be sped up significantly using parallelism. NOTES:: [Adminitrivia V1/Prg/19950529] END:: STAN//CS-TR-84-1003
