result

#include <gempba/utils/result.hpp>  // included automatically via gempba.hpp

result pairs a score with a task_packet. It represents a candidate solution found during the search: the quality of the solution and its serialized form ready for retrieval or transmission.

node_manager stores the best result seen so far and returns it after the run completes. In multiprocessing mode, the worker that found the best solution reports it to the center as a result; the center selects the overall best when collecting final answers.

Constructor

result(const score& score, task_packet task_packet);

Construct from a quality value and its associated serialized solution.

Accessors

[[nodiscard]] score get_score() const;

Returns the quality value of this solution.

[[nodiscard]] task_packet get_task_packet() const;

Returns the serialized form of the solution.

[[nodiscard]] int get_score_as_integer() const;

Convenience wrapper around score::get_loose<int>(). Useful for quick comparisons when the score type is known to be integral.

Sentinels and comparison

static const result EMPTY;

Represents the absence of a solution. Has a score of -1 and an empty task_packet. Used as the initial value before any solution is found.

bool operator==(const result&) const;
bool operator!=(const result&) const;

Compare both score and task_packet.
