SUMMARY:Cornflow: a flexible open source deployment server for optimization engines
DESCRIPTION:Speaker: Franco Peschiera\, PhD\, Baobab soluciones \nIn the last decade\, the cloud has motivated many business in OR to offer their optimization services through REST APIs. From modellers to solver suppliers\, each platform provides access to the owner’s product. Most of the times this access is tied to the use of the product. \nIn combinatorial optimization there is no silver-bullet (or free lunch)\, each solution method (MIP model\, CP model\, meta-heuristic\, add-hoc heuristic\, etc.) is suited to solve different problems. Only offering a limited range of solution methods risks losing the power to solve some problem efficiently. \nFinally\, except a few exceptions (VRP\, TSP)\, most problems do not have a clear data interface that is standardized. This makes it hard to benchmark different approaches to a given problem. \nTo address these problems (vendor lock\, no-free-lunch\, lack of standardization)\, Cornflow was created as a free (as in freedom) problem-agnostic and solver-agnostic deployment server for optimization problems. It hosts problems as flexible data-structures (json schemas) and solution methods as code (usually python code but not exclusively). This allows full customization of problems and their solution methods. For example a VRP-like problem can be solved with Concorde\, a CP-SAT model\, column-generation with gurobi or a 2-opt heuristic. While a Nurse-Rostering-like problem can be solved with a traditional MIP model\, Timefold or some clever matheuristic. \nWe believe that by keeping the deployment server open\, we will make it easier for problem providers (i.e.\, industry) and solution providers (i.e.\, academia) to build on top of each other’s work and collaborate more easily. \nAbout the speaker: \nFranco Peschiera is an engineer\, a programmer and a scientist. He loves solving puzzles\, organizing stuff and customer service. During his free (and not-so-free) time he’s a father\, a cyclist and a professional skeptic. \nFranco has a double degree in industrial engineering from the PUCP (Lima) and UPM (Madrid) universities and a PhD in Industrial Engineering from ISAE-SUPAERO (Toulouse). He founded a successful OR software (baobab soluciones) company based in Madrid where he worked 10 years as various roles\, including project leader\, chief technical officer\, and consultant in several optimization projects in the car\, aerospace\, oil and pharmaceutic industries\, among many others. \nHe also founded a yet-to-be-succesful clothing-rental company based in Lima/Rome (HackPacking)\, is the proud maintainer of the PuLP mathematical modelling library and maintains several other open source tools for Operations Research. You can find him in: LinkedIn and github. \n  \n\n\n\n\n\n\n\n\n\nEURO Practitioners’ Forum past and planned activities are available to the Forum members\, as well as the wider public. \nVisit the website and register as a member for free\, to get the regular updates on all activities: EPF Member registration page. The recordings and details from previous webinars are also available on this website. \nFollow the Forum on Twitter and LinkedIN \, and feel free to get in touch. \n\n\n
