Graph labeling is a central topic in combinatorial optimisation that involves assigning numerical or categorical labels to vertices or edges of a graph subject to specific constraints. This framework ...

Normal phase HPLC is a valuable technique for the separation of polar and hydrophilic compounds and for isomer separation. Normal phase HPLC requires a polar stationary phase combined with non or ...

This research topic explores the theoretical foundations and practical applications of graph labeling and coloring problems, both of which are central to modern combinatorics and computer science.
