Could anyone tell me what is an optimal basis(definition) when using revised simplex method to solve linear programming problem? I google it, but I cannot find the definition of optimal basis, except someone mentioned that if the reduced cost is less than zero, but the reduced cost is a vector, how could I say it is less than zero or not? Thank you very much!
