The Optimization 2026 conference aims to convene researchers and practitioners from diverse fields and backgrounds who share common interests in Optimization. This prestigious event is internationally recognized as a significant forum for discussion and the exchange of ideas. It marks the 11th edition of a series of international conferences on optimization, organized in Portugal under the auspices of APDIO (the Portuguese Operations Research Society). The conference will be held at ISEG – Lisbon School of Economics and Management of the Universidade de Lisboa, from July 20-22, 2026.
