5 CONSTRAINT SATISFACTION PROBLEMS
aima.cs.berkeley.eduIn some cases, we can reduce CONSTRAINTS integer constraint problems to finite-domain problems simply by bounding the values of all the variables. For example, in a scheduling problem, we can set an upper bound equal to the total length of all the jobs to be scheduled.
Constraint Satisfaction Problems
www.cs.toronto.educonstraint satisfaction problem. • A Constraint Satisfaction Problem consists of 3 components 1. A set of variables. 2. A set of values for each of the variables. 3. A set of constraints between various collections of variables. We must find a value …
Constraint Satisfaction Problems (CSPs)
www.cs.colostate.eduConstraint satisfaction problems n A CSP is composed of: q A set of variables X 1,X 2,…,X n with domains (possible values) D 1,D 2,…,D n q A set of constraints C 1,C 2, …,C m q Each constraint C i limits the values that a subset of variables can take, e.g., V 1 ≠ V 2 4
Constraint Satisfaction Problems (CSPs)
www.ccs.neu.eduCSPs All search problems The space of all CSPs – states are defined in terms of variables – goals are defined in terms of constraints A CSP is defined by: 1. a set of variables and their associated domains. 2. a set of constraints that must be satisfied.
