Abstract: Mixed-integer linear programs are widely used to model optimization problems involving both discrete and continuous variables, but remain computationally challenging due to the combinatorial ...

A unit fraction is any fraction where the numerator is 1, for example \(\frac{1}{4}\). A non-unit fraction is a fraction where the numerator is not 1, for example \(\frac{4}{5}\). Mixed fractions are ...
