void UpdateIdealpoint(Individual *ind, double *ideal_point, int obj_num)

Update the ideal point ideal_point with given individual ind.

Parameter:
	ind: Individual, default=None* The pointer to the given individual. ideal_point: double, default=None* The pointer to the ideal point which will be updated. It's a 1D array of double. obj_num: int, default=None The number of objectives.
Returns:
	void

void UpdateNadirpoint(Individual *ind, double *nadir_point, int obj_num)

Update the ideal point nadir_point with given individual ind.

Parameter:
	ind: Individual, default=None* The pointer to the given individual. ideal_point: double, default=None* The pointer to the nadir point which will be updated. It's a 1D array of double. obj_num: int, default=None The number of objectives.
Returns:
	void

int RankSumTest(const std::vector<double>& array1, const std::vector<double>& array2)

Do the ranksum test between the two given arrays.

Parameter:
	array1: std::vector<double>, default=None The first array which will attend ranksum test. array2: std::vector<double>, default=None The second array which will attend ranksum test.
Returns:
	res: int The result of ranksum test. 0 means no significant difference and 1 means has significant difference with 5% significance level.

int SignRankTest(const std::vector<double>& array1, const std::vector<double>& array2)

Do the sign rank test between the two given arrays.

Parameter:
	array1: std::vector<double>, default=None The first array which will attend sign rank test. array2: std::vector<double>, default=None The second array which will attend sign rank test.
Returns:
	res: int The result of sign rank test. 0 means no significant difference and 1 means has significant difference with 5% significance level.
