Question

Which among the following is a characteristic observed in constraint programming?

(a) No changes can made on definition of the system

(b) Only independent variables are applied

(c) Strict norms to compute a value

(d) Definition of relationship between variables and constraints

This question was posed to me during an interview.

My doubt is from Building CRA on SDR Architecture in chapter Cognitive Radio Architecture of Cognitive Radio

Answer 1

Right choice is (d) Definition of relationship between variables and constraints

To explain: Constraint programming is applied to a group of problems thatpermit the conversion of a problem into variables. It should be possible to define the problem as a mathematical equation. A final model is constructed based on the relationship between the variables and the constraints. The model is used to compute the value of variables.
