Subject: This week in ACL2 Date: Mon, 09 Jun 2003 10:46:42 -0500 From: Robert Bellarmine Krug Greetings, This week I, Robert, will talk about some of my work with ACL2 and arithmetic. This talk will be divided into two parts --- 1. New changes to ACL2, and 2. My arithmetic-4 library. In part 1, I will describe modifications to ACL2 which allow linear arithmetic to use the conclusions of forward- chaining rules. I will also describe changes which allow type reasoning to (weakly) use linear arithmetic. I will also present motivational examples for both these changes. In part 2., I will introduce my arithetic-4 library which I have recently gotten permision to distribue. This will be an introductory talk, and will probably be followed by a more comprehensive talk in a couple of weeks. Robert
