European Symposium on Algorithms
open-in-new
<h2 id="history">History</h2> <p>The first ESA was held in 1993 and contained 35 papers. The intended scope was all research in algorithms, theoretical as well as applied, carried out in the fields of <a href="/facts/Computer_science/lN3pEyPz">computer science</a> and <a href="/facts/Discrete_mathematics/XdRUnzUL">discrete mathematics</a>. An explicit aim was to intensify the exchange between these two research communities. </p> <h3>Workshop on Algorithms Engineering</h3> <p>In 2002, ESA incorporated the conference Workshop on Algorithms Engineering (WAE). In its current format, ESA contains two distinct tracks with their own programme committees: a track on the design an <a href="/facts/Analysis_of_algorithms/pStoBgBn">analysis of algorithms</a>, and a track on engineering and applications, together accepting around 70 contributions. </p> <h2 id="esa-awards">ESA Awards</h2> <h3>ESA Test-of-Time Award</h3> <p>The ESA Test-of-Time Award (ESA ToTA) recognizes outstanding papers in algorithms research that were published in the ESA proceedings 19–21 years ago and which are still influential and stimulating for the field today.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> Because the Workshop on Algorithms Engineering (WAE) merged in with ESA, the Steering Committee decided that the papers from WAE 1999 to WAE 2001 were also to be considered. </p> ESA Test-of-Time Award<table><tbody><tr><th>Year</th><th>Winners</th><th>Award Committee</th></tr><tr><td>2022</td><td>Marianne Durand, Philippe Flajolet: Loglog Counting of Large Cardinalities (Extended Abstract).
