When running IPOPT, if my objective function returns Inf or NaN (to reject the point and cut alpha in the line search), the solver exits with: "EXIT: Invalid number in NLP function or derivative detected,". We use cookies for various purposes including analytics. Given a system transforming a set of inputs to output values, described by a mathematical function f, optimization refers to the generation and selection of a best solution from some set of available alternatives, by systematically choosing input values from within an allowed set, computing the value of the function, and recording the best value found during the process. That is, it doesn’t take your full program and “turns it into C” – rather, the result makes full use of the Python runtime environment. Homebrew’s package index. Then fsolve computes a full finite-difference approximation in each iteration. It is also configured with various optimization solvers including Gurobi, Ipopt, PIPS-NLP, DSP, and CPLEX.

The long answer: Julia is a general purpose programming language designed to challenge R and Matlab with keeping all functionality intact while adding new features to increase productivity, readability and finally: perfor. Any other linear or nonlinear equality or inequality constraint will not necessarily be satisfied until the solver has finished converging at the final iteration (if it can get to a point that satisfies termination conditions). Thus, Julia performed more than 5-times faster than Python on a single processor, and about 7. JuMP is a domain-specific modeling language for mathematical optimization embedded in Julia. 7 or Julia v1. UPDATE: You can try L-BFGS with IPOPT, see under Quasi-Newton in the documentation.
