EvoStar

EvoStar, or Evo*, is an international scientific event devoted to evolutionary computation held in Europe. Its structure has evolved over time and it currently comprises four conferences: EuroGP the annual conference on Genetic Programming, EvoApplications, the International Conference on the Applications of Evolutionary Computation, EvoCOP, European Conference on Evolutionary Computation in Combinatorial Optimisation, and EvoMUSART, the International Conference on Computational Intelligence in Music, Sound, Art and Design. According to a 2016 study EvoApplications is a Q1 conference, while EuroGP and EvoCOP are both Q2. In 2021, EuroGP, EvoApplications and EvoCOP obtained a CORE rank B.

Other conferences in the area include the ACM Genetic and Evolutionary Computation Conference (GECCO), the IEEE Congress on Evolutionary Computation (CEC) and the bi-annual Parallel Problem Solving from Nature (PPSN).

History
Originally run under the name of EvoWorkshops, the event was an outcome of EvoNet, the Network of Excellence in Evolutionary Computing, funded by the European Commission under the Information Societies Technology Programme, FP5-IST. EvoNet was coordinated by Terry Fogarty and managed by Jennifer Willies, both at Edinburgh Napier University at the time, and had more than 100 participating nodes. After EvoNet funding ended, support was provided by Edinburgh Napier University to help EvoStar to continue over the years. In 2014 the SPECIES Society was set up to provide an appropriate legal structure for future organisation and support of the EvoStar conferences. SPECIES support of EvoStar became effective in 2017, with Edinburgh Napier University taking a sponsoring role.

Editions
The first edition was held in Paris in 1998. Subsequent editions took place in Göteborg (1999), Edinburgh (2000), Lake Como (2001), Kinsale (2002), Essex (2003), Coimbra (2004), Lausanne (2005), Budapest (2006), Valencia (2007, first edition under the name EvoStar ), Napoli (2008), Tübingen (2009), Istanbul (2010), Torino (2011), Málaga (2012), Vienna (2013), Granada (2014), Copenhagen (2015), Porto (2016), Amsterdam (2017), Parma (2018) and Leipzig (2019). In 2020, Evostar was to be held in Seville, Spain, but due to COVID-19 pandemic, it was finally held as an online conference. In 2021 Evostar was expected to be held in Seville, but was again held as an online conference. In 2022 Evostar was held in Madrid, Spain, as a hybrid event (in person and online). It was followed in 2023 by Brno in the Czech Republic, and in 2024 by Aberystwyth, both again in person and via the Internet. In 2025 EvoStar will take place in Trieste.

Areas
The areas covered include both theoretical aspects and applications of evolutionary computation, in particular genetic programming, and hybridization with other metaheuristics.

Competitions
A number of competitions have been held throughout the history of EvoStar, specifically in 2010 and 2011. These have been frequently related to the evolutionary games and arts and design areas. Of particular relevance has been the Mario AI Championship

Art exhibitions
The first curated evolutionary art exhibition linked to EvoStar was held in Budapest in 2006, in the ArtPool P60 space, and run under the title Process revealed. Nineteen works from 8 different countries were presented, with Janis Jefferies and Tim Blackwell acting as curators.

The following year, ArtEscapes - Variations of life in the media arts was launched in Valencia in conjunction with the 2007 edition of EvoStar, and spanning 5 more weeks. Anna I Esparcia-Alcázar and Paulo Urbano curated 22 works, with artists coming from 11 countries around the globe.
