Functors (symbols) = strings that begin with lower case. Picat provides three solver modules: cp, sat, and mip. Carefully graduated in scope, each worksheet introduces only a limited number of new ideas, and gives some guidance for practising them. The objective of the attached exercises is to give some practical experience with: the constraint solvers of Oz/Mozart the constraint handling rules (in SICStus Prolog), the interval CLP in Prolog IV. Uses full program examples to lead you step-by-step through writing: an adventure game, an intelligent data-base, an expert system and an order entry program. 4 Although recursion can be used over many different data structures, one of the most frequently encountered in NLP environments is the list. 3: Sum of squares of two largest numbers out of three, Prolog Version The problem, as stated, has a completely straight-forward solution, because the problem statement is limited to numbers: sicp1(X, Y, Z, SumSquares) :- msort([X,Y,Z], [_,A,B]), SumSquares is A^2 + B^2. Unlike many other programming languages, Prolog is intended primarily as a declarative programming language. The tutorials will work through (some of) the solutions. Two Books in one app!.
