Linear optimization problems are defined as problems where the objective function and constraints are all linear. The Wolfram Language has a collection of algorithms for solving linear optimization problems with real variables, accessed via LinearOptimization, FindMinimum, FindMaximum, NMinimize, NMaximize, Minimize and Maximize.Optimization approaches can be classified according to the characteristics of both the given problem and the solution method into the following general types: 1. Unconstrained optimization. 2. Linear programming. 3. Other mathematical programming techniques. 4. Heuristic algorithms. 5. Simulation-based optimization. Linear Optimization often goes by the name Linear Programming (LP). The word "Programming" should not be confused with computer programming which in fact it antedates. As originally used, the term refers to the timing and magnitude of actions to be carried out so as to achieve a goal in the best possible way. Linear algebra is the study of linear operations in vector spaces. An example of a vector space is the infinite set of all possible Cartesian coordinates in two dimensions in relation to a fixed point referred to as the origin, and each vector (i.e., a 2-dimensional coordinate) can be viewed as a member of this set.
