WG1.1 - Continous Algorithms
To provide a forum for international collaboration and for the dissemination of research and applications of continuous algorithms and complexity.
Many problems in natural science, engineering, social science and business have continuous models. Hence the scope of WG 1.1 is algorithms and especially computational complexity of algorithms for solving continuous models.
