This is required to turn an inequality into an equality where a linear combination of variables is greater than or equal to a given constant in the former.

Webb7 juni 2024 · 1,417 A slack variable does not change the problem, just its representation. If you have a constraint f ( x) ≤ b with x variables and b a constant, then you replace it with f ( x) + λ = b and λ ≥ 0 which amounts to the same thing. λ is a new variable called a slack variable (cause it "picks up the slack" of the original inequality). WebbSimilar to slack variable, to convert an inequality to equality, we subtract a variable from the left side of a greater than or equal to constraint This is done to reduce/remove the excess on the left side For instance, X + 3Y >= 20 To convert this inequality into an equality, we subtract a surplus variable “s” from the L.H.S.
