This paper present a new approach, combined pseudo- parallelism evolution technique based on sub-population competition with parent mutation mechanism, for automatic topology optimization of multilayer feedforward neural networks. It allows that two networks with different number of individuals can be crossed to a new valid "child" network. The calculation result of an example shows that...
A series of novel 3,4-dihydro-2H-benzo[1,4]oxazine derivatives has been designed and synthesized as 5-HT 6 receptor antagonists. Many of the compounds displayed subnanomolar affinities for the 5-HT 6 receptor and good brain penetration in rats. The relationship of structure and lipophilicity to hERG inhibition of this series of compounds is discussed.
