On behalf of the Programme and Organizing Committee of SYM-OP-IS 2021, it is our pleasure to invite you to participate in this year's Symposium on Operational Research. We hope that your contribution will help to continue the tradition and quality of the Symposium.

We encourage all contributions within and beyond the scope of specific scientific disciplines and countries, with the aim of furthering international cooperation. In addition, we warmly invite collaborators and students of Prof. Mladenović to contribute to a Special section on VNS method and applications, dedicated to Prof. Nenad Mladenović celebrating his 70th birthday and 45 years of research work.


SYM-OP-IS is an international symposium which traditionally gathers researchers, practitioners and educators in operations research to discuss and present their theoretical and practical research results in formal and an informal setting. The goal of the Symposium is to inspire knowledge exchange within and among different fields of optimization.
