The primal bound of the problem. This value can be a number or a string. If it's a string, it can represent a number, 'NA', 'nan', 'inf', '+inf', '-inf', '-nan', or an empty string.
The optimization direction, which can either be 'max' for maximization problems or 'min' for minimization problems.
primalBound.
If the primal bound is an empty string, 'na', 'nan', or '-nan', it returns -Infinity for 'max' direction and Infinity for 'min' direction.
If the primal bound is 'inf' or '+inf', it returns Infinity, and for '-inf', it returns -Infinity.
Otherwise, it converts the primal bound into a number.Generated using TypeDoc
This function is used to calculate the primal bound of an optimization problem, which can either be a maximization or minimization problem.
