11/24 You may find a hastily constructed trace through the backward chaining algorithm to be useful.
11/22 Please be aware of the following error in the unify algorithm in the text. It would have you replace constants with variables. (See the errata page.): Page 303, Figure 10.3, line -1: Change "{x/var}" to "{var/x}"

You will not be penalized for submission by Tuesday 11:59pm.

11/21 Answers to the example files are posted in the projects section.

Example 17 has been simplified in order to avoid any chance of infinite recursion.

11/20 Changes to project two:
  • Tier 3 is now extra credit. Tier 1, Tier 2, and Tier 3 are worth 40, 30, and 7 points respectively for a possible total of 77/70 points.
  • You may submit your code by 11:59pm, Tuesday 11/26 and your report by 8:30am, Wednesday, but you will receive a 15% late penalty. If you want to take this option, you will need to use the project identifier LATE_project_java or LATE_project_c with the turnin command. No projects will be accepted after that time.
