Mixed-integer programming techniques for decomposing IMRT fluence maps using rectangular apertures
We consider a matrix decomposition problem arising in Intensity Modulated Radiation Therapy (IMRT). The problem input is a matrix of intensity values that are to be delivered to a patient via IMRT from some given angle, under the condition that the IMRT device can only deliver radiation in rectangular shapes. This paper studies the problem of minimizing the number of rectangles (and their assoc...
متن کاملCombinatorial Benders cuts for decomposing IMRT fluence maps using rectangular apertures
We consider the problem of decomposing Intensity Modulated Radiation Therapy (IMRT) fluence maps using rectangular apertures. A fluence map can be represented as an integer matrix, which denotes the intensity profile to be delivered to a patient through a given beam angle. We consider IMRT treatment machinery that can form rectangular apertures using conventional jaws, and hence, do not need so...
متن کاملMixed and Integer Linear Programming Using Automata Techniques
We present a comprehensive overview of automata techniques for deciding first order logical theories. These techniques are useful in Integer Linear Programming and Mixed Integer Linear Programming, which in turn have wide applications in diverse areas of computer science and engineering. We have several goals in this paper. The first is to solidify the theory underpinning the automata technique...
متن کاملMixed Integer Linear Programming Formulation Techniques
A wide range of problems can be modeled as Mixed Integer Linear Programming (MILP) problems using standard formulation techniques. However, in some cases the resulting MILP can be either too weak or to large to be effectively solved by state of the art solvers. In this survey we review advanced MILP formulation techniques that result in stronger and/or smaller formulations for a wide class of p...
متن کاملALTERNATIVE MIXED INTEGER PROGRAMMING FOR FINDING EFFICIENT BCC UNIT
Data Envelopment Analysis (DEA) cannot provide adequate discrimination among efficient decision making units (DMUs). To discriminate these efficient DMUs is an interesting research subject. The purpose of this paper is to develop the mix integer linear model which was proposed by Foroughi (Foroughi A.A. A new mixed integer linear model for selecting the best decision making units in data envelo...
