Communications in Combinatorics and Optimization is devoted to publishing original and innovative research papers in combinatorics and optimization, peripherally interdisciplinary. The journal aims to provide a complete and reliable source of information on current developments in the fields. Publishing articles with high quality as rapidly as possible and making them available to interested researchers worldwide is the main scope. The journal encourages contributions from the three important parts of graph theory, combinatorics, and optimization; and their application. The first part includes structural graph theory, extremal graph theory, algebraic graph theory, chemical graph theory, and random graphs. The second part consists of combinatorial design, combinatorial enumeration, coding theory, the combinatorial probabilistic method, etc. The third part includes scheduling, network optimization, integer programming, constrained and unconstrained optimization, game theory, algorithm design, and complexity analysis, etc.
