The solver’s method “findOptimalSolution” now has an optional third parameter: public Solution findOptimalSolution(Objective objective, Var objectiveVar, OptimizationStrategy optStrategy);
where “optStrategy” can be one of 3 standard constants:
OptimizationStrategy.NATIVE – defined by a concrete implementation
OptimizationStrategy.BASIC – provided by a common JSR-331 implementation using a solution operator
OptimizationStrategy.DICHOTOMIZE – provided by a common JSR-331 implementation
The optimization process may be controlled by two different time limits set by the following methods of the interface Solver:
setTimeLimit(millis) – a number of milliseconds for a search of one solution
setTimeLimitGlobal(millis) – a number of milliseconds for the entire search of an optimal solution
The TCK now contains an additional 4 packages:
org.jcp.jsr331.test – mandatory JUnit tests that check compliance of different CP solvers to the standard
org.jcp.jsr331.samples – various constraint satisfaction and optimization problems that demonstrate the use of JSR-331
org.jcp.jsr331.linear.samples – various linear optimization problems that may be executed with any CP or LP solvers
org.jcp.jsr331.hakan – a collection of test problems contributed by Hakan Kjellerstrand
