Class KLinTerm

java.lang.Object
com.artelys.kalis.KTerm
com.artelys.kalis.KLinTerm

public class KLinTerm extends KTerm
This class represent a linear term of the form Sum(coeffs[i].lvars[i]) + cst

Example :

KProblem p(...);
KIntVarArray X(...);

KLinTerm linTerm;

linTerm = 3 * X[0];
linTerm = linTerm + 5;
linTerm = linTerm + 2 * X[1];
linTerm = linTerm - 3 * X[2] + 5 * X[3];
linTerm = linTerm - 7;
// these lines are equivalent to :
// linTerm = 3 * X[0] + 2 * X[1] - 3 * X[2] + 5 * X[3] - 2

// posting the constraint  3 * X[0] + 2 * X[1] - 3 * X[2] + 5 * X[3] - 2 >= 5
// will be converted into  -3 * X[0] - 2 * X[1] + 3 * X[2] - 5 * X[3] + 7 <= 0
p.post(linTerm >= 5);
