Examine how constraint satisfaction problems differ from other search problems with respect to the type of states they use during the search.

Question $11$Answer

a$.$

Constraint satisfaction problems use states defined by heuristics only, whereas other search problems use states defined by explicit rules.

b$.$

Other search problems use constraint$-$based states while constraint satisfaction problems do not impose any constraints on the states.

c$.$

There is no difference; constraint satisfaction problems use states in the same way as all other search problems.

d$.$

Constraint satisfaction problems use states that are defined by the values of a set of variables and the goal is to find a set of values for those variables that satisfy all constraints, in contrast to other search problems that may not have such explicitly defined variables and constraints.
