Fascinated by neighborhood search, dynamic programming, and computational complexity? Check our latest paper at Transportation Science on pickup-and-delivery problems. Surprisingly large neighborhoods can be explored in a surprisingly small time!

It's a great pleasure to share that João Vilela, a student from DEI - PUC-Rio whom I co-advise with Bruno Fanzeres, was awarded the Best Dissertation in Operations Research by the Brazilian Society in 2022.

It's been a pleasure to be part of this great series!

The people of Brazil have spoken. I’m looking forward to working with Lula to strengthen the partnership between our countries, to deliver results for Canadians and Brazilians, and to advance shared priorities – like protecting the environment. Congratulations, Lula!

Happy to be part of this team! Bruno Fanzeres João Vilela

The EURO Meets NeurIPS 2022 #VehicleRouting Competition is officially started! It focuses on a dynamic VRPTW and gathers the #MachineLearning and #ORMS communities around a common problem. Check our kickstart material and key dates here:

Recent paper with Bruno Fanzeres, Claudio Contardo and João Vilela.

New exponential-size neighborhoods for the pickup-and-delivery problem. Optimal solutions are attained for most problems with up to 30 nodes in a *single* local-search descent, giving 1,000x speedup over previous algorithms! Check our paper here:

Ontem, tive o prazer em ter o primeiro orientando de doutorado defendendo sua tese. Parabéns, doutor Victor Abu!
Yesterday, I had the pleasure of having my first doctoral student defending his thesis. Congratulations, Doctor Victor Abu!

I've just published my first Julia Package: CARPData.jl. It just load CARP instances easily:
