Discrete optimization


Discrete optimization is a branch of optimization in applied mathematics and computer science.

Scope

As opposed to continuous optimization, some or all of the variables used in a discrete mathematical program are restricted to be discrete variables—that is, to assume only a discrete set of values, such as the integers.

Branches

Three notable branches of discrete optimization are:
These branches are all closely intertwined however since many combinatorial optimization problems
can be modeled as integer programs or constraint programs,
any constraint program can be formulated as an integer program and vice versa,
and constraint and integer programs can often be given a combinatorial interpretation.
