It is not the best option to regard it as a non-convex QP. A product of a binary variable and a continuous variable is not really bilinear (or non-linear). For example, the nonlinear constraint $$z_{ij} \geq x_{ij}y_{ij}$$ could be replaced with $$z_{ij} \geq y_{ij} - y_{\max}(1-x_{ij})\\ z_{ij} \geq y_{\min}x_{ij}$$ (the RHS of the second line could be \$...
