Welcome to the BBOB workshop series!

The Black-box Optimization Benchmarking (BBOB) workshop series provides an easy-to-use toolchain for benchmarking black-box optimization algorithms for continuous and mixed-integer domains and a place to present, compare, and discuss the performance of numerical black-box optimization algorithms. The former is realized through the Comparing Continuous Optimizers platform (Coco).

So far, twelve workshops have been held (in 2009, 2010, 2012, 2013, 2015, 2016, 2017, 2018, 2019, 2021, 2022, and in 2023 at GECCO and in 2015 at CEC). The next workshop is going to take place during GECCO 2025.

Generally, seven benchmark suites are available:

  • bbob containing 24 noiseless functions
  • bbob-noisy containing 30 noisy functions
  • bbob-biobj containing 55 noiseless, bi-objective functions, generated from the bbob suite
  • bbob-largescale containing 24 noiseless functions in dimension 20 to 640
  • bbob-mixint containing 24 noiseless mixed-integer functions
  • bbob-biobj-mixint containing 92 noiseless, bi-objective, mixed-integer functions
  • bbob-constrained containing 10 noiseless functions with varying number of constraints.

Continuous Submission of Benchmarking Data

Since 2020, we also welcome submissions of data from benchmarking experiments on the above test suites throughout the year. Please open a submission issue at https://github.com/numbbo/coco/issues/new/choose .
