The construction of a program that generates crossword puzzles is discussed. As in a recent paper by Dechter and Meiri, we make an experimental comparison of various search techniques. The conclusions to which we come differ from theirs in some areas-although we agree that directional arc consistency is better than path-consistency or other forms of(More)
Simulators used in research on autonomous mobile robots have been criticized for their tendency to change the nature of the problems the robot control architecture has to solve. In this paper we address those arguments, and find that under certain conditions simulators can be a valuable tool to supplement research with physical robots. We conclude with(More)
Some features of computer programs can make the programs easier to use by enabling users to interact with them in the familiar ways they interact with other people. Including these features is hard, however, and doing a good job at it is even harder. We present some of these features, and compare the pros and cons of including them in a computer program. We(More)
