Theoretical Computer Science

Usually, computer science seems like a practical field that involves studying, building, and working closely with computers. However, a subclass of this discipline also centers on the mathematical factors of the same. This is called theoretical computer science, and its focal point differentiates it from other branches of computer science: the rigorous mathematical approach it takes. This discipline falls under the umbrella of discrete mathematics, which is the study of countable or discontinuous mathematical structures.

Safe Datalog Rule: A Datalog rule is of the form:p :- q1, ..., qn. where n>0 and p is a positive atomic formula and q1, ..., and qn are positive or negative atomic formulas. A positive atomic formula is of the form:r(x1, ..., xm) and a negative atomic formulas of the form:not r(x1, ..., xm) where m>0 and r is a relation name and x1 , ..., xm are either numbers or variables. Relation names and variables are made up of alphabetic letters or digits and start with a lower-case alphabetic letter. Even though the variables are made up of lower and upper-case letters, these should be considered case-insensitive. For example, cno, CNO, cNO, etc all should be treated as the same variable. Some examples of Datalog rules are given below: ancestor(x1, y1) :- parent(x1, y1). teaches(tno,cno) :- faculty(tno), course(cno), assigned(tno,cno). p(x,y) :- q(2,x), r(u,45,z), s(a,b,22). p(x,y,z) :- q(x), not r(y,20), s(x,z). A Datalog rule is considered “Safe” if all variables that appear to the left…
