Comparison of the quality of the plans acquired by three different algorithms for five clinical data sets in dose conformity to the target (CN), and fluence-map complexity (number of segments and MI).The proposed method enables for attaining the similar CN with much fewer segments and simpler fluence-map complexity (MI) than the existing methods can do.
