The Constraint Logic Programming module is a project module (COS498X). It is advisable that you take both COS407 and COS451 if you want to do the CLP project.
you need to speak to Tertia Horne - the lecturer for the module. Once she says its okay for you to do the module then you contact Professor vd Poll (is that even the right name...) and let him/her know you will do the constraint logic project
