History

Checkers, also called Draughts, is a 1952 video game developed by British computer scientist Christopher Strachey. It is one of the first computer programs in the early history of video games, possibly the first game to display visuals on an electronic screen, and the first game written for a general-purpose computer. It first became operational during the summer of that year on the Ferranti Mark 1 computer at the University of Manchester. In Checkers, the player competes against a rudimentary artificial intelligence in a simulation of the board game of the same name; the game ends when all of either player's pieces have been captured or obstructed by the opponent.

2012-06-01T00:00:00Z — DTIC ADA570802: Evaluating Security Requirements in a General-Purpose Processor by Combining Assertion Checkers with Code Coverage
The problem of malicious inclusions in hardware is an emerging threat, and detecting them is a difficult challenge. In this research, we enhance an existing method for creating assertion-based dynamic checkers, and demonstrate how behavioral security requirements can be derived from a processor's architectural specification, then converted into security checkers that are part of the processor's design. The novel contributions of this research are - We demonstrate the method using a set of assertions, derived from the architectural specification, on a full-scale open-source general-purpose processor design, called OpenRISC. Previous work used only a single assertion on a toy processor design. - We demonstrate the use of our checker-generator tool, called psl2hdl, which was created for this research. - We illustrate how the method can be used in concert with code coverage techniques, to either detect malicious inclusions or greatly narrow the search for malicious inclusions that use rare-event triggers.

1978-01-01T00:00:00Z — Checkers
A playable version of the board game of Checkers. The player controls the 12 checkers at the bottom of the screen and attempts to remove the 12 checkers at the top of the screen, controlled by the computer. A player can only move his checkers diagonally toward his opponent's side of the board. A checker can be jumped when two opposing checkers are adjacent to each other and there is an empty space directly across the checker being jumped. If there's a checker in the board that a player can jump, he is forced to do so. If a checker reaches the other side of the board, that checker is kinged and is allowed to move and jump both back and forth in diagonal movements. The game is won by the player who removes all of his opponent's checkers from the board. Description courtesy of MobyGames via a CC license
