Towards general performance diagrams to define optimum profile and lead modifications with regard to transmission error in spur and helical gears
Jérôme Bruyère,Philippe Velex +1 more
TL;DR: In this paper , a semi-analytical definition of optimum combinations of profile relief and lead crown minimising the time-variation amplitudes of transmission error is presented. But no closed-form solutions can be found, general trends are clearly identified, making it possible to define optimum tooth modifications with reasonable precision.

An overview of evolutionary algorithms in multiobjective optimization
TL;DR: Current multiobjective evolutionary approaches are discussed, ranging from the conventional analytical aggregation of the different objectives into a single function to a number of population-based approaches and the more recent ranking schemes based on the definition of Pareto optimality.
