Struct coin_cbc::raw::Model

pub struct Model { /* private fields */ }

A CBC MILP model.

Their methods are a direct translation from the C API. For documentation, see the official API documentation.

    &mut self,
    row_starts: &[c_int],
    col_indices: &[c_int],
    weights: &[f64],

)

Adds multiple SOS constraints num_rows: the number of SOS constraints to add row_starts: The indices at which each new constraint starts in the col_indices array, plus one last element that indicates the size of col_indices array. col_indices: The index of each variable to include in the constraints. You create this array by concatenating the indices of the columns in each constraint.
