Cryptarithmetic column constraints
WebHigher-order constraints involve 3 or more variables, e.g., cryptarithmetic column constraints Example: Cryptarithmetic Variables: F T U W R O X1 X2 X3 Domains: {0,1,2,3,4,5,6,7,8,9} Constraints: Alldiff (F,T,U,W,R,O) O + O = R + 10 · X1 X1 + W + W = U + 10 · X2 X2 + T + T = O + 10 · X3 X3 = F, T ≠ 0, F ≠ 0 Webe.g., cryptarithmetic column constraints Preferences(soft constraints), e.g., red is better than green often representable by a cost for each variable assignment →constrained …
