Evaluation of the impact of evolution strategy parameters on the optimization of the markers distribution on the VAD membrane

Abstract

The paper investigates the influence of selection and operators of evolutionary strategy on the reconstruction of the shape of the pneumatic membrane surface of the extracorporeal cardiac support pump. Sets consisting of selection, mutation and crossing were assessed. The study was conducted in the context of optimizing the distribution of markers on the surface of the flaccid membrane. The arrangement of the markers is important from the point of view of modeling the shape of the membrane surface and ultimately determining the stroke volume. The experiments were carried out for a convex membrane with a known mathematical description. The value of the error of mapping the determined shape of the membrane with respect to the shape of the reference surface was assumed as the criterion of the assessment.
