Many computational problems arising in artificial intelligence,computer science and elsewhere can be representedas constraint satisfaction and optimization problems. In thisshort survey we discuss an approach that is related to thealgebraic component of multiple-valued logic and that hasproved to be very succesful in studying the complexity ofconstraint satisfaction.
