True or false: there exists a differentiable function $f(x,y)$ whose tangent plane at $(1, 2)$ is $2x + z= 3$? The plane $x + 2y = 5$ is a vertical plane, but tangent ...
function_tabulator provides a thin, well‑tested wrapper around pwlf and numpy for turning smooth mathematical functions into compact piecewise‑linear approximations ("tabulations"). You give it a ...
Abstract: Linear approximations of the AC power flow equations are of great significance for the computational efficiency of large-scale optimal power flow (OPF) problems. Put differently, the ...
