FdConfig: A Constraint-Based Interactive Product Configurator
  We present a constraint-based approach to interactive product configuration.
Our configurator tool FdConfig is based on feature models for the
representation of the product domain. Such models can be directly mapped into
constraint satisfaction problems and dealt with by appropriate constraint
solvers. During the interactive configuration process the user generates new
constraints as a result of his configuration decisions and even may retract
constraints posted earlier. We discuss the configuration process, explain the
underlying techniques and show optimizations.
