A technique is presented for replacing long-term interlocking of shared data by the possible repetition of unprivileged code in case a version number (associated with the shared data) has been changed by another process.Expand

This report describes the third in a series of computer experiments designed to explore the extent to which computers may feasibly be used in doing formal mathematics.Expand

Abstract : The subject of this report is mechanical theorem proving, and in it are described two computer programs that represent an approach different from the usual ones based on the Herbrand… Expand

SAM V, the fifth program, uses a cathode ray tube as the principal interface between the mathematician and a high speed digital computer for semi-automated mathematics.Expand
