From joel@.MISSING-HOST-NAME. Fri Mar 22 12:32:56 2002 Date: Sun, 17 Mar 2002 22:45:46 -0500 (EST) From: Joel Seiferas To: CSC484 Subject: Some guidance on 5.19-5.21 Some guidance on 5.19-5.21: These exercises test our understanding of the two-part proof of Theorem 5.25: 5.19 is analogous to the needed case from Theorem 5.19, and 5.20 can be derived from it by an adaptation of the simulation in Section 5.3.2. 5.21 can be handled by yet another recycling of the entire 2-part strategy. (I hope my notes on the proof of Theorem 5.25 make it more accessible.) Joel
