◆ setSolutionDimension()

void dart::optimizer::MultiObjectiveProblem::setSolutionDimension	(	std::size_t	dim,
		std::size_t	integerDim = `0u`
	)

virtual

Sets the dimension of the solution.

The element type of the solution can be either double or int. In the case that the solution partially contains integers, we assume the integer part takes place the tail of the solution, and the size of the integer part is integerDim. For example, a solution vector can be [floating1, floating2, ..., int1, int2].

Note that the dim represents the whole dimension of the solution so that the dimension of floating-point part is to be (dim - integerDim).

By default, we assume the solution is homogeneously floating-point type ( i.e., integerDim is zero).

Parameters

[in]	dim	Total dimension of the solution.
[in]	integerDim	The dimension of integer part in the solution.

◆ setUpperBounds()

void dart::optimizer::MultiObjectiveProblem::setUpperBounds ( const Eigen::VectorXd & ub )

Sets upper bounds for optimization parameters.
