Configuration helper

The Config template creates the objects representing tree and default policies used by the solvers. Additionally it defines several type aliases used by other parts of the library.

ISMCTS::Config

Defined in <ismcts/config.h>

template<
    class Move,
    template<class> class SeqTree = UCB1,
    template<class> class SimTree = EXP3,
    template<class> class Default = RandomElement
> struct Config;

SeqTree and SimTree are the tree policies used for sequential and simultaneous moves, respectively. These should be functors with the signature Node* (std::vector<Node*> const&), where Node is the node class associated with the policy; this is further described in Tree Policies. Default specifies the default policy, which is used to simulate a non-terminal game state to completion upon creation of new nodes by the tree policy. This should be a functor with signature Move const& (std::vector<Move> const&), returning one of the given moves.

Note: policy arguments need not be const or reference, but the return values must come from the vectors provided. Policy operators are never called with empty vectors by the solver.

Constructor

Config(SeqTree<Move> seq = SeqTree<Move>{},
       SimTree<Move> sim = SimTree<Move>{},
       Default<Move> d = Default<Move>{}
);
