Computer search for trees with minimal ABC index

open access: yesApplied Mathematics and Computation, 2012
The ABC index is a degree-based molecular structure descriptor, that found chemical applications. Finding the connected graph(s) of a given order whose ABC index is minimal is a hitherto unsolved problem, but it is known that these must be trees. In this paper, by combining mathematical arguments and computer-based modeling we establish the basic ...

ABC Algorithm-Based Subblocks Set Design for OFDM With All Index Modulation

IEEE Communications Letters, 2020
In this letter, we propose a low complexity artificial bee colony (ABC) algorithm based subblocks set design to maximize the diversity gain of orthogonal frequency division multiplexing with all index modulation (OFDM-AIM), which is inspired by OFDM with index modulation (OFDM-IM).
