Conference History and Growth: A Comprehensive Timeline (1976-2025)

Since its inception in 1976, this conference has evolved from a modest gathering of researchers into a massive global event. Spanning nearly five decades, the event has served as a critical hub for presenting accepted papers—peer-reviewed research contributions—and fostering collaboration among international experts.

The journey began in Philadelphia, USA, and has since traversed the globe, visiting major cities across North America, Europe, Asia, and Australia. This growth is reflected not only in the geographical diversity of the venues but also in the dramatic increase in both attendance and the volume of scientific contributions.

Throughout the 1990s and 2000s, the conference solidified its international status. The number of accepted papers consistently climbed, surpassing the 1,000-mark by 1997 in Munich. The 2010s saw a further surge in participation, culminating in a record-breaking shift during the 2020-2021 period when the transition to virtual formats allowed for unprecedented accessibility, peaking at over 16,000 attendees.

In recent years, the conference has returned to in-person formats with renewed vigor. The 2024 event in Seoul and the upcoming 2025 event in Hyderabad indicate a new era of scale, with attendance figures consistently exceeding 4,000 and accepted papers reaching historic highs.
