2.1. What are Optimization Solvers?

Optimization solvers are algorithms or software tools that find the best possible solution to a mathematical problem. These problems often involve maximizing or minimizing a specific objective function, subject to a set of constraints. In simpler terms, an optimization solver seeks to find the “sweet spot” within a given set of parameters and limitations. Optimization solvers are crucial in various fields for decision-making and problem-solving.

2.2. Key Components of an Optimization Problem

To understand how optimization solvers work, it’s important to identify the key components of an optimization problem:

Objective Function: This is the mathematical expression that the solver aims to maximize or minimize. It represents the goal of the optimization problem.
Decision Variables: These are the variables that the solver can adjust to find the optimal solution.
Constraints: These are the limitations or restrictions that the decision variables must adhere to. Constraints define the feasible region within which the optimal solution must lie.
Feasible Region: The set of all possible solutions that satisfy the constraints.
Optimal Solution: The solution within the feasible region that yields the best value for the objective function.

2.3. Types of Optimization Problems

Optimization problems can be classified into various types based on the nature of the objective function and constraints:

Linear Programming (LP): The objective function and constraints are linear.
Nonlinear Programming (NLP): The objective function or constraints are nonlinear.
Integer Programming (IP): Some or all decision variables must be integers.
Mixed-Integer Programming (MIP): A combination of continuous and integer decision variables.
Convex Optimization: The objective function is convex, and the feasible region is a convex set.
