Abstract:
For the first time, boundary estimators are presented for consecutive clusters of particles that possibly correspond to global potential minima where the potential depends on the number of particles (either negative decrease as with the Lennard Jones and Morse potentials, or growth positive as with the Thomson potential). Their main characteristic is that they establish that the global potential of a cluster is limited by two frontier estimators that depend on the global potentials of the previous and subsequent clusters.
This benefits global particle cluster optimization methods to distinguish solutions. Thanks to information shared on the Internet, the estimators have been successfully verified for clusters under various potentials, for example, Thomson, Lennard Jones, Morse, and for Quantum Lennard Jones for xenon, argon and neon. New Morse results are reported by verifying that previously reported results did not satisfy these estimators.
