I have experienced that the so called pioneer researchers (not all) in the field of chemical graph theory are doing partiality. They don't want others to publish their research work in reputed(In fact became their own journals) journals. They simply reject papers and give silly reasons like "your work is unsuitable for our journal" after more than a year or sometimes early. In fact, they accept some other papers from their groups even though the quality of the paper is lower than ours. I am in dilemma whether to continue research in Chemical Graph Theory or to quit. Let me know your suggestions.
