The authors describe how they have used constraints and constraint hierarchies in three different systems: ThingLab II, a system written in Smalltalk-80 for building user interfaces;HCLP, a new programming language that integrates constraint hierarchies with logic programming;and Kaleidoscope, another programming language that combines constraint hierarchies with imperative programming constructs (state and assignment), as well as with object-orientedprogramming. Also described are the algorithms these systems require for finding solutions to constraint hierarchies.
