Method Detail

setup

public void setup()

Overrides:

setup in class LPEngineLpSolveImpl

engineType

public LPEngine.EngineType engineType()

Description copied from interface: LPEngine

Returns what engineType is actually used by the implementing class. This knowledge can be used for variable mappings etc.

Specified by:

engineType in interface LPEngine

Overrides:

engineType in class LPEngineLpSolveImpl

Returns:

the engineType used.

isFeasible

public boolean isFeasible()

Description copied from interface: LPEngine

Assess whether is at least one solution

Specified by:

isFeasible in interface LPEngine

Overrides:

isFeasible in class LPEngineLpSolveImpl

Returns:

true iff the LP is feasible

solve

public java.util.Map<java.lang.Integer,java.lang.Double> solve()

Description copied from interface: LPEngine

Solve the LP and return the best variable assignment

Specified by:

solve in interface LPEngine

Overrides:

solve in class LPEngineLpSolveImpl

Returns:

A non-empty map with variable-assignment pairs. An empty map if no solution is found

solveAndValue

public org.processmining.framework.util.Pair<java.util.Map<java.lang.Integer,java.lang.Double>,java.lang.Double> solveAndValue()

Description copied from interface: LPEngine

Solve the LP and return the best variable assignment and the assignment value.

Specified by:

solveAndValue in interface LPEngine

Overrides:

solveAndValue in class LPEngineLpSolveImpl

Returns:

a non-empty map with assignment and associated value. Empty map and -1 if no solution.

solveAndValueNative

public org.processmining.framework.util.Pair<double[],java.lang.Double> solveAndValueNative()

Description copied from interface: LPEngine

Solve the LP and return the best variable assignment and the assignment value.

Specified by:

solveAndValueNative in interface LPEngine

Overrides:

solveAndValueNative in class LPEngineLpSolveImpl

Returns:

a non-empty map with assignment and associated value. Empty map and -1 if no solution.

solveNative

public double[] solveNative()

Description copied from interface: LPEngine

Solve the LP and return the best variable assignment

Specified by:

solveNative in interface LPEngine

Overrides:

solveNative in class LPEngineLpSolveImpl

Returns:
