Computation should be a good blend of theory and practice, and researchers in the field should create algorithms to address real world problems, putting equal weight on analysis and implementation. Experimentation and simulation can be viewed as yielding to refined theories or improved applications. The Workshop on Computation: Theory and Practice (WCTP)-2011 was the first workshop organized jointly by the Tokyo Institute of Technology, the Institute of Scientific and Industrial Research Osaka University, the University of the Philippines Diliman, and De La Salle University Manila devoted...
