Linear Programming(LP)（part 2）

When do we use linear programming technique? Explain mathematical formulation of Linear programming Problem (LPP).

Solving an integer programming problem by rounding off answers obtained by solving it as a linear programming problem (using Simplex LP), we find that

Which of the following statements is true regarding the solution methods for solving a linear programming (LP) model?Group of answer choicesThe Simplex algorithm is not the basis of most LP optimization software.The computer solution method uses the Evolutionary algorithm.The graphical solution method can handle LP models with any number of decision variables and constraints.None of the above.

Modelling a fixed cost problem as an integer linear program requiresGroup of answer choicesadding the fixed costs in the objective function.using 0-1 variables.using multiple-choice constraints.using LP Relaxation.

In a linear programming (LP) problem, if the slack value for a particular constraint is negative, it indicates:Group of answer choicesThe constraint is not feasible and cannot be satisfied.The constraint is binding, and all resources are fully utilized.The constraint has surplus resources and is not fully utilized.The slack value cannot be negative; it is always positive.
