From joel@.MISSING-HOST-NAME. Tue Mar 5 01:22:49 2002 Date: Mon, 4 Mar 2002 16:11:35 -0500 (EST) From: Joel Seiferas To: CSC484 Subject: Comments on 5.15 I'm not sure I got everyone's hard-exercise estimates, but I think every respondent did cite number 15. Hint no. 1: Make sure you've noted the authors' correction. Implicit in the text's hint: We're talking about the same setting as is Lemma 5.17--shared-memory systems, without shared writing. What we really showed in that lemma: Changing a single input cannot lead to disjoint valence. A natural follow-up exercise on might ask about: Can we still obtain the stronger result (Theorem 5.25) under the changed definition? Joel
