Many real-world and theoretical problems may be modeled in this general framework. In mathematics, conventional optimization problems are usually stated in terms of minimization. Local maxima are defined similarly. A large number of algorithms proposed for solving nonconvex problems—including the majority of commercially available solvers—are not capable of making a distinction between locally optimal solutions and globally optimal solutions, and will treat the former as actual solutions to the original problem. Optimization problems are often expressed with special notation. Dantzig studied at that time.

This can be viewed as a particular case of nonlinear programming or as generalization of linear or convex quadratic programming. It is a generalization of linear and convex quadratic programming. LP, SOCP and SDP can all be viewed as conic programs with the appropriate type of cone. This is not convex, and in general much more difficult than regular linear programming.

For specific forms of the quadratic term, this is a type of convex programming. The special class of concave fractional programs can be transformed to a convex optimization problem. This may or may not be a convex program. In general, whether the program is convex affects the difficulty of solving it. Robust optimization targets to find solutions that are valid under all possible realizations of the uncertainties. Usually, heuristics do not guarantee that any optimal solution need be found. On the other hand, heuristics are used to find approximate solutions for many complicated optimization problems.

Disjunctive programming is used where at least one constraint must be satisfied but not all. It is of particular use in scheduling. Adding more than one objective to an optimization problem adds complexity. For example, to optimize a structural design, one would desire a design that is both light and rigid. When two objectives conflict, a trade-off must be created. There may be one lightest design, one stiffest design, and an infinite number of designs that are some compromise of weight and rigidity. If it is worse than another design in some respects and no better in any respect, then it is dominated and is not Pareto optimal.
