示例1:
/**
* Free all ressources.
*/
Constraint::~Constraint(void) {
Factor *fact = facts;
while(fact) {
Factor *next = fact->next();
delete fact;
fact = next;
}
sys->removeConstraint(this);
}示例2: coefficient
// Overload
double Constraint::coefficient(ilp::Var *var) const {
ASSERT(var);
Var *lvar = sys->getVar(var);
ASSERT(lvar);
for(Factor *fact = facts; fact; fact = fact->next())
if(fact->variable() == lvar)
return fact->coefficient();
ASSERT(false);
}示例3: dump
/**
* Dump the constraint to the given output.
* @param out Used output.
*/
void Constraint::dump(elm::io::Output& out) {
bool first = true;
for(Factor *fact = facts; fact; fact = fact->next()) {
if(first)
first = false;
else
out << " + ";
out << (int)fact->coefficient() << " ";
if(fact->variable()->variable()->name())
out << fact->variable()->variable()->name();
else
out << "_" << fact->variable()->column();
}
}示例4: add
/* !!NOTE!!
* Collection of factors would be more fast if they was stored in a dynamic
* vector. Not done now for debugging purpose but should be performed.
* Another interesting optimization should be to remove factor whose coefficient
* become null.
*/
void Constraint::add(double coef, ilp::Var *var) {
if(var == 0)
cst -= coef;
else {
Var *lvar = sys->getVar(var);
ASSERT(lvar);
for(Factor *fact = facts; fact; fact = fact->next())
if(fact->variable() == lvar) {
fact->add(coef);
return;
}
facts = new Factor(coef, lvar, facts, var);
}
}示例5: resetRow
/**
* Reset the value used in the given row by the current constraint.
* @param row Row to reset.
*/
void Constraint::resetRow(double *row) {
ASSERT(row);
for(Factor *fact = facts; fact; fact = fact->next())
row[fact->variable()->column()] = 0;
}示例6: fillRow
/**
* Fill a row of the lp_solve matrice with the current constraint.
* @param row Row to fill.
*/
