A two-stage sequential linear programming approach to IMRT dose optimization [PDF]
Physics in Medicine and Biology, 2010 The conventional IMRT planning process involves two stages in which the first stage consists of fast but approximate idealized pencil beam dose calculations and dose optimization and the second stage consists of discretization of the intensity maps followed by intensity map segmentation and a more accurate final dose calculation corresponding to ...

Scalarizing cost-effective multiobjective optimization algorithms made possible with kriging [PDF]
, 2007 The use of kriging in cost-effective single-objective optimization is well established, and a wide variety of different criteria now exist for selecting design vectors to evaluate in the search for the global minimum.

Recurring Two-Stage Evolutionary Programming: A Novel Approach for Numeric Optimization
IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2011 In the application of evolutionary algorithms (EAs) to complex problem solving, it is essential to maintain proper balance between global exploration and local exploitation to achieve a good near-optimum solution to the problem. This paper presents a recurring two-stage evolutionary programming (RTEP) to balance the explorative and exploitative ...
