VCL Among the Winners of the Open Optimization Competition 2020

VCL has Received the Second Prize in the Open Optimization Competition 2020, Held in GECCO 2021


The Open Optimization Competition 2020 concerns code contributions made to the Nevergrad and IOHprofiler open source tools. Nevergrad is an open source platform for derivative-free optimization, while IOHprofiler is a tool for benchmarking iterative optimization heuristics such as local search variants, evolutionary algorithms, model-based algorithms, and other sequential optimization techniques.

VCL’s contribution to the Nevergrad platform was the introduction of a benchmark for gradient-free optimizers, targeting the real-world problem of 3D Performance Capture. The code in question can be found here.

The code contribution is accompanied by the paper “Zeroth-Order Optimizer Benchmarking for 3D Performance Capture”, authored by A. Doumanoglou, P. Drakoulis, K. Christaki, N. Zioulis, V. Sterzentsenko, A. Karakottas, D. Zarpalas and P. Daras that will be presented at GECCO 2021. More information about the paper can be found here.

Visual Computing Lab

The focus of the Visual Computing Laboratory is to develop new algorithms and architectures for applications in the areas of 3D processing, image/video processing, computer vision, pattern recognition, bioinformatics and medical imaging.
