Linear programming finally made sense once the constraints, objective, and simplex logic were explained step by step.
Helped me translate a word problem into a clean optimization model much faster than my class notes ever did.
I was stuck on a Solver assignment and got clear help with the setup, feasible region, and final interpretation.

Linear Programming Concept Explanations (WHY)
Each item below is a one-sentence, exam-ready explanation. Live WHY pages are linked; proposed WHYs are included for academic completeness and future expansion.
Linear Programming (Live WHY Pages)
- Why is the Big-M Method important? — Big-M enforces constraints by penalizing artificial variables so the solver can start from an initial feasible basis.
- Why understand the Two-Phase Simplex Method? — Two-phase finds feasibility first (Phase I) then optimizes the true objective (Phase II) without huge penalty constants.
- Why do pivot rules matter in the simplex method? — Pivot rules control progress, avoid cycling, and influence numerical stability and speed.
- Why do basic feasible solutions correspond to corner points? — Setting nonbasic variables to zero intersects constraints at extreme points of the feasible region.
- Why does every LP have an optimal solution at a corner point? — A linear objective over a convex polytope attains its optimum at an extreme point or along an edge of extreme points.
- Why identify basic feasible solutions before solving? — Simplex moves between BFS corner points, so identifying them clarifies feasibility and search structure.
- Why can a linear program be unbounded? — If the feasible region allows indefinite movement in an improving direction, the objective can increase without limit.
- Why do multiple optimal solutions occur? — When the objective is parallel to a binding edge, every point on that edge achieves the same optimum.
- Why does degeneracy occur? — A BFS can have more binding constraints than needed, creating zero basic variables and potential stalling or cycling.
- Why do shadow prices matter? — Shadow prices quantify the marginal value of relaxing a constraint.
- Why do reduced costs matter? — Reduced costs show how much an objective coefficient must improve before a nonbasic variable should enter the solution.
- Why does sensitivity analysis matter? — It shows how robust the solution is to changes in costs, resource limits, and constraints.
- Why does linear programming use duality? — Duality links primal decisions to resource prices, providing bounds, interpretation, and optimality certificates.
Integer & Binary Optimization (Live WHY Pages)
- Why do linear, integer, and binary programming models capture real-world decisions? — Integer decisions represent yes/no and indivisible choices that linear models can’t express.
- Why do linear, integer, and binary models give managers a disciplined way to optimize? — They convert messy constraints into solvable models with transparent tradeoffs.
- Why do linear, integer, and binary models help organizations optimize? — They enforce feasibility across many constraints while optimizing a measurable goal.
- Why does branch and bound solve integer programming efficiently? — It prunes large parts of the search tree using LP relaxations as bounds.
- Why does the knapsack model capture real-world trade-offs? — It formalizes picking a best subset under a capacity limit.
- Why is integer programming harder than linear programming? — Integrality makes the feasible set nonconvex, turning the problem into combinatorial search.
- Why are binary decision variables essential? — They model on/off choices and logical constraints.
- Why does rounding LP solutions fail? — Rounding can violate constraints or destroy optimal structure.
Network & Structured Models (Live WHY Pages)
- Why does the transportation model matter? — It models shipping flows efficiently and often solves faster via specialized methods.
- Why does the max-flow min-cut theorem matter? — It equates the best feasible flow with the tightest capacity bottleneck.
- Why does the Hungarian Method solve the assignment problem efficiently? — It finds a minimum-cost perfect matching using reduced costs and augmenting steps.
