WebThe Slack or Surplus column in the Solution Report shows how tight the constraint is. If a constraint is completely satisfied as an equality, then slack/surplus is zero. If slack/surplus is positive, then this tells you how many more units of the variable could be added to the optimal solution before the constraint becomes an equality. WebSlack or Surplus Variables It can be shown that for any inequality constraint, the product of the variables of the constraint’s slack or surplus variable and the constraint’s shadow price must be equal to 0. This implies that any constraint whose slack or surplus variable is >0 will have a zero shadow price.
