Nettetlinear approximation. Natural Language. Math Input. Extended Keyboard. Examples. Nettet28. jun. 2024 · Actually, I tried one reformulation that utilizes the following identity: ab = ((a+b)/2)^2 - ((a-b)/2))^2. Afterwards, the quadratic terms are piecewise-linearized. The results are accurate to great extent, but the major problem with this formulation is the involvement of large number of binary variables in piecewise linearization method for …

If you got two binary-variables x and y, you can add a new auxiliary binary variable z = x*y by these constraints: z <= x. z <= y. z >= x + y - 1. As i can't follow your task (incomplete pseudo-code) you will have to do the rest yourself, using the newly introduced variable z. Share. prof miftahudin ipb https://jshefferlaw.com
