Last week I had the pleasure of being invited to the Second annual JuMP-dev workshop, which happened in June 27-29, 2018 at Bordeaux, France. I’ve presented the packages from the Julia Smooth Optimizers organization, and had a very good time meeting with the JuMP developers. For those still …

The comparison of algorithms is an active area of work. When we start learning algorithms, or more advanced programming, we learn of different ways of doing the same complex task. The most usual first example is sorting, which introduces a series of different ways to sort a single array, such as …

Secondly, download the appropriate Gurobi version clicking on Gurobi Optimizer. In my case, it is Linux 64 bits. Where to download this is optional, …

Hoje ministrarei mais um minicurso de Julia na UFPR. Desta vez será no IX Simpósio de Análise Numérica e Otimização da UFPR. Por enquanto, deixo esta página apenas com o link para o notebook que utilizarei: aqui.

This is a continuation of this post. And again, you can follow the commands of this post in the asciinema. If you followed along last post, you should know the basics of our NLPModels API, including CUTEst access. One thing I didn’t explore, though, was constrained problems. It’d …

A couple of weeks ago me and Professor Dominique Orban have finally made a release of CUTEst.jl, a wrapper for the CUTEst repository of problems for nonlinear optimization (which I’ve mentioned before). Along with this release, we’ve done a release of NLPModels.jl, the underlying …

Nos dias 30 de Novembro à 2 de Dezembro de 2016 acontece o primeiro Simpósio de Métodos Numéricos em Engenharia. Neste simpósio darei um minicurso sobre Julia. Deixo aqui o material preliminar para os alunos do minicurso, ou interessados. Notebook (necessário) exemplo.jl (necessário) HTML estático …

For some time, one of my concerns is bibliography management. See my projects page if you have interest on working with something like that. In the past, what we had was simply writing all your bibliographies directly on a .tex file. Then, if you needed to write again, you would copy-paste it …

Semana passada, nos dias 22 a 24 de Fevereiro aconteceu o VIII Simpósio de Análise Numérica e Otimização. Nesse evento, eu apresentei um minicurso de Julia com foco em Otimização não Linear. Entre 10 e 15 pessoas participaram no total, entre alunos de graduação, de pós-graduação, e professores. O …
