Enum NetworkSimplex.SolutionStatus

java.lang.Object
  java.lang.Enum<NetworkSimplex.SolutionStatus>
      org.graphstream.algorithm.networksimplex.NetworkSimplex.SolutionStatus

All Implemented Interfaces:

Serializable, Comparable<NetworkSimplex.SolutionStatus>

Enclosing class:

NetworkSimplex

public static enum NetworkSimplex.SolutionStatus
extends Enum<NetworkSimplex.SolutionStatus>

The status of the current solution.

Enum Constant Summary

INFEASIBLE
The problem is infeasible, some of the supply/demand constraints cannot be satisfied.

OPTIMAL
The problem is feasible and bounded.

UNBOUNDED
The problem is unbounded (this happens when the graph contains an uncapacitated negative cost cycle).

UNDEFINED
The current solution is outdated.

Method Summary

static NetworkSimplex.SolutionStatus	valueOf(String name) Returns the enum constant of this type with the specified name.
static NetworkSimplex.SolutionStatus[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

UNDEFINED

public static final NetworkSimplex.SolutionStatus UNDEFINED

The current solution is outdated. This is the value when the graph has changed since the last call of NetworkSimplex.compute()

OPTIMAL

public static final NetworkSimplex.SolutionStatus OPTIMAL

The problem is feasible and bounded. The current solution is up to date and optimal.

INFEASIBLE

public static final NetworkSimplex.SolutionStatus INFEASIBLE

The problem is infeasible, some of the supply/demand constraints cannot be satisfied. The current solution is up to date.

UNBOUNDED

public static final NetworkSimplex.SolutionStatus UNBOUNDED

The problem is unbounded (this happens when the graph contains an uncapacitated negative cost cycle). The current solution is up to date.

Method Detail

values

public static NetworkSimplex.SolutionStatus[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NetworkSimplex.SolutionStatus c : NetworkSimplex.SolutionStatus.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NetworkSimplex.SolutionStatus valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
