Method Detail

getPolicy

ResolutionPolicy getPolicy()

Returns:

the ResolutionPolicy of the problem

isOptimization

default boolean isOptimization()

Returns:

true iff the problem is an optimization problem

getBestLB

Number getBestLB()

Returns:

the best lower bound computed so far

getBestUB

Number getBestUB()

Returns:

the best upper bound computed so far

updateBestLB

void updateBestLB(Number lb)

States that lb is a global lower bound on the problem

Parameters:

lb - lower bound

updateBestUB

void updateBestUB(Number ub)

States that ub is a global upper bound on the problem

Parameters:

ub - upper bound

updateBestBounds

default void updateBestBounds(IBoundsManager b)

States that b is global bounds on the problem

Parameters:

b - lower and upper bounds

getBestSolutionValue

Number getBestSolutionValue()

Returns:

the best solution value found so far (returns the initial bound if no solution has been found yet)

resetBestBounds

default void resetBestBounds()

Reset best bounds to the initial domain of the objective variables
