slack variable
[/slæk ˈvɛriəbəl/]
nounpl: slack variables
variável de folga
1. In linear programming and optimization, a non-negative variable added to a linear inequality constraint to convert it into an equality equation
The slack variable was introduced to transform the inequality constraint into an equality for the simplex method.
A variável de folga foi introduzida para transformar a restrição de desigualdade em uma igualdade para o método simplex.
2. A variable representing the unused capacity or surplus in a constraint
If a factory can produce 100 units but only produces 80, the slack variable equals 20 units.
Se uma fábrica pode produzir 100 unidades mas produz apenas 80, a variável de folga é igual a 20 unidades.
This is specialized terminology used primarily in academic and professional contexts within operations research, mathematics, and industrial engineering. The term is consistent across both Brazilian Portuguese and European Portuguese. It is fundamental to understanding linear programming solutions, particularly in the simplex algorithm, which is taught in business schools, engineering programs, and management courses throughout Portugal and Brazil.
