Comparative Study of Different Memetic Algorithm Configurations for the Cyclic Bandwidth Sum Problem [PDF]

open access: yes, 2018
The Cyclic Bandwidth Sum Problem (CBSP) is an NP-Hard Graph Embedding Problem which aims to embed a simple, finite graph (the guest) into a cycle graph of the same order (the host) while minimizing the sum of cyclic distances in the host between guest’s adjacent nodes.
