a probability, which is a function of their fitness (roulette wheel selection with each parent having a slot with a size proportional to its fitness) to achieve a smoother probability curve. This prevents good......
. The dynamic loadings induced by rail-wheel interaction first transfer to the track structure via sleeper, then to the substructure. In this process, the sleepers play a role in transforming train... because the substructure of high-speed railway mainly reflects low frequency vibration induced by the train loads. Use the equipment weight to simulate the static rail-wheel loads Pj caused by train......
