The algorithms to solve an integer programming problem are either through heuristics (such as with ant colony optimization problems), branch and bound methods, or total unimodularity, which is often used in relaxing the integer bounds of the problem (however, this is usually not optimal or even feasible).

Distinguish between integer programming problem and linear programming problem?
Integer programming is a subset of linear programming where the feasible region is reduced to only the integer values that lie within it.
What is an explanation of zero-one integer Programming?
Definition of 'Zero-One Integer Programming' An analytical method consisting of what amounts to a series of "yes" (1) and "no" (0) answers to arrive at a solution. In the world of finance, such programming is often used to provide answers to capital rationing problems, as well as to optimize investment returns and assist in planning, production, transportation and other issues.
Will the solution to an linear programming problem always consist of integers?
No, it will not. In fact, there is a special branch of linear programming which is called integer programming and which caters for situations where the solution must consist of integers.
How do you solve integer subtraction problems?
It depends on the problem. An integer subtraction can be one number, take away another number.
What are two characteristics of an irrational number?
An irrational number is not an integer or whole number and it can't be expressed as a fraction.

What is NN IN maths?
N squared. It could be the Cartesian plane restricted to integer values, as required for integer linear programming problems.
Can a linear programming problem have two optimal solutions?
No. However, a special subset of such problems: integer programming, can have two optimal solutions.
What is integer programming?
Integer programming is a special kind of an optimising problem where the solution must be an integer.
Distinguish between integer programming problem and linear programming problem?
Integer programming is a subset of linear programming where the feasible region is reduced to only the integer values that lie within it.

What is the difference between linear and integer programming?
Integer programming is a method of mathematical programming that restricts some or all of the variables to integers. A subset of Integer programming is Linear programming. This is a form of mathematical programming which seeks to find the best outcome in such a way that the requirements are linear relationships.
Explain how implicit enumeration is used to solve integer programming problems.?
Implicit enumeration (or "additive algorithm") is used to solve 0/1 LP problems
Why are integer programming problems more difficult to solve than linear programming problems?
In both cases the constraints are used to produce an n-dimensional simplex which represents the "feasible region". In the case of linear programming this is the feasible region. But that is not the case for integer programming since only those points within the region for which the variables are integer are feasible.The objective function is then used to find the maximum or minimum - as required. In the case of a linear programming problem, the solution must lie on one of the vertices (or along one line in 2-d, plane in 3-d etc) of the simplex and so is easy to find. In the case of integer programming, the optimal solution so found may contain one or more variables that are not integer and so it is necessary to examine all the points in the immediate neighbourhood and evaluate the objective function at each of these points. This last requirement makes integer programming solutions more difficult to find.
How do you find the answer to an integer problem?
It depends on the problem: you may have to use integer programming rather than linear programming.
