What is Operational Research?
Operational Research is an analytical approach to problem-solving and decision-making, particularly valuable in organizational management. It involves breaking down complex problems into fundamental components and solving them through structured mathematical analysis.

What is Assignment Problem?
The Assignment Problem is a core combinatorial optimization problem within operations research. It focuses on finding the maximum weight matching (or minimum weight perfect matching) in a weighted bipartite graph. The goal is to assign agents to tasks in a way that minimizes the total cost, ensuring each agent is assigned to exactly one task and each task is assigned to exactly one agent.

What is Transportation Problem?
The Transportation Problem is a specialized linear programming problem aimed at minimizing the cost of distributing products from multiple sources to various destinations.

What is Linear Programming?
Linear Programming (LP), also known as linear optimization, is a technique used to achieve the best possible outcome (e.g., maximum profit or minimum cost) in a mathematical model where requirements are represented by linear relationships.

What is Sequencing Problem?
A Sequencing Problem involves determining the optimal order in which a set of jobs (operations) should be assigned to a finite number of service facilities (machines or equipment) to optimize outputs in terms of time, cost, or profit.

What is Game Theory?
Game Theory is a branch of Operational Research that analyzes strategies for competitive situations. It considers how the outcome of one participant's actions depends on the actions of other participants. It is applicable in diverse fields like war, business, and biology.
