# What is either or constraints and if/then constraints?

## What is either or constraints and if/then constraints?

Either Or and If Then Constraints- Integer Linear Programming Illustrative Applications. The transformation does not change the “or” or “dependence” nature of the constraints. It simply uses a mathematical trick to present them in the desired format of “and” constraints.

## What is binary LP?

Zero-one linear programming (or binary integer programming) involves problems in which the variables are restricted to be either 0 or 1. Any bounded integer variable can be expressed as a combination of binary variables.

What are the integer programming models?

Integer programming expresses the optimization of a linear function subject to a set of linear constraints over integer variables. The statements presented in Linear programming: a production planning example are all linear programming models.

### What are logical constraints?

Logical constraints are one particular kind of discrete or numerical constraints. OPL and CPLEX can translate logical constraints automatically into their transformed equivalent that the discrete (MIP) or continuous (LP) optimizers of IBM ILOG CPLEX can process efficiently.

### Are binary constraints linear?

A binary constraint, in mathematical optimization, is a constraint that involves exactly two variables. Linear programs in which all constraints are binary can be solved in strongly polynomial time, a result that is not known to be true for more general linear programs.

What does binary constraint do?

A binary constraint, in mathematical optimization, is a constraint that involves exactly two variables. Linear programs in which all constraints are binary can be solved in strongly polynomial time, a result that is not known to be true for more general linear programs. …

## Is binary a code?

Binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1. (See the table below for how the decimal numbers from 0 to 10 are represented in binary.) …

## What is a binary constraint in Excel Solver?

A binary constraint is one in which the variable must equal either 0 or 1. To specify a binary constraint, use the Cell Reference box to identify the variable cell that must be binary and then select the bin operator from the unnamed drop-down list box.

What is the difference between linear and integer programming?

Linear programming maximizes (or minimizes) a linear objective function subject to one or more constraints. Mixed integer programming adds one additional condition that at least one of the variables can only take on integer values. The technique finds broad use in operations research.

### What is a 0 1 integer model?

Zero-one integer programming (which can also be written as ‘0-1’ integer programming) is a mathematical method of using a series of binary functions; in particular, yes (‘1’) and no (‘0’) answers to arrive at a solution when there are two mutually exclusive options.
