What we have learnt
- Optimization is the process of finding the best solution from a set of possible solutions.
- Linear programming optimizes a linear objective function subject to linear constraints.
- Nonlinear programming involves optimizing a nonlinear objective function with potentially complex constraints.
Key Concepts
- -- Linear Programming (LP)
- A mathematical method for determining a way to achieve the best outcome in a given mathematical model represented by linear relationships.
- -- Nonlinear Programming (NLP)
- An optimization process that deals with objective functions that are nonlinear in nature.
- -- Gradient Descent
- An iterative optimization algorithm used for finding the minimum of a function by moving along the slope of the function.
- -- Simplex Method
- A widely used algorithm for solving linear programming problems by moving along the edges of the feasible region.
- -- Duality
- Concept in linear programming where every optimization problem has a corresponding dual problem, helping to derive insights about the original problem.
