Scaling jeopardizes Simplex convergence
回答済みHi, We're solving energy system models (often LPs without integrality constraints) and we're trying to improve the numerical properties of these models by scaling the input values. The scaling appr...

I'm not an expert but it seems you are solving a mixed-integer LP (MILP). Indications for this are that in the log it says "Root barrier log..." and "Root crossover log...". I don't know exactly wh...

barrier and crossover restart
回答済みI'm trying to solve an energy system model with ~2*10^6 rows and columns and ~7*10^6 non-zeros (after presolve) with barrier and crossover on gurobi 8.1.1.. The problem seems to have a large numer...
