MIC is the main event focusing on the progress of the area of metaheuristics and their applications. MIC provides an opportunity to the international research community in metaheuristics to discuss recent research results, to develop new ideas and collaborations, and to meet old and make new friends in a relaxed atmosphere. MIC has a long tradition in the metaheuristics community that dates back to the first MIC held in Breckenridge, Colorado (USA, 1995).
