To make it more clear, let’s consider an optimization problem of the following standard form: \begin{equation} \begin{array}{cl} {\min} & {f_0(x)}\\ {\mathrm{s.t.}} & {f_i(x)\leqslant 0,\quad i=1,\cdots,m}\\ {} & {h_i(x)=0,\quad i=1,\cdots,p}\\ \end{array} \end{equ…

You’re right that that can be a confusing topic. We should probably add more explanation to the JuMP docs. A key realization is that: The sign convention is arbitrary. I could assume that \lambda was non-positive if I put a - sign in front of the summation JuMP uses the duality conventions from c…

If a model is INFEASIBLE, does the dual of its constraints have any explicit meaning?
