In addition, we have found that a small number of monomers have been found by the GA to promote a small HOMO-LUMO gap. All of those monomers exhibit small HOMO-LUMO gaps on their own, which helped promote a small HOMO-LUMO gap in the full oligomer. However, no other monomers with a small HOMO-LUMO gap were found by the GA, which shows that the GA has its flaws. While the randomness built into the GA can sometimes miss a potential candidate it is still a faster and more efficient method than an exhaustive search over the vast chemical space.
