Claris CAD Claris CAD Claris CAD was a two-dimensional computer-aided design program for Apple Inc. Macintosh. Claris CAD was developed in 1988 by Claris Corporation in a joint effort with Craig S. Young of Computer Aided Systems for Engineering (CASE). It was based on MacDraw II and Young's earlier CAD application, "EZ-Draft". Version 1 was released in 1989 for Macintosh computers running System Software 6 or later. The initial releases were plagued with bugs, especially with the bundled plotter driver. Development halted in June 1991 with the release of version 2.0.3. Currently, Claris CAD can be run on older Macintoshes using the
Computer-assisted proof Computer-assisted proof A computer-assisted proof is a mathematical proof that has been at least partially generated by computer. Most computer-aided proofs to date have been implementations of large proofs-by-exhaustion of a mathematical theorem. The idea is to use a computer program to perform lengthy computations, and to provide a proof that the result of these computations implies the given theorem. In 1976, the four color theorem was the first major theorem to be verified using a computer program. Attempts have also been made in the area of artificial intelligence research to create smaller, explicit, new proofs of mathematical theorems from
