  6. 14. Approaches to accelerate methods for solving systems of equations arising in nonlinear optimization

    Author : David Ek; Anders Forsgren; Jacek Gondzio; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optimization; mathematical programming; interior-point methods; approximate solutions to systems of linear equations; method of conjugate gradients; quasi-Newton methods; modified Newton methods; Ickelinjär optimering; matematisk programmering; inre-punktsmetoder; approximativa lösningar till linjära ekvationssystem; konjugerade gradientmetoden; kvasi-Newtonmetoder; modifierade Newtonmetoder.; Optimization and Systems Theory; Optimeringslära och systemteori;

    Abstract : Methods for solving nonlinear optimization problems typically involve solving systems of equations. This thesis concerns approaches for accelerating some of those methods. In our setting, accelerating involves finding a trade-off between the computational cost of an iteration and the quality of the computed search direction. READ MORE

  7. 15. Radiation Therapy Patient Scheduling: An Operations Research Approach

    Author : Sara Frimodig; Per Enqvist; Jan Kronqvist; Mats Carlsson; Willem-Jan van Hoeve; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiation therapy scheduling; patient scheduling; multi-appointment scheduling; operations research; integer programming; constraint programming; column generation; Schemaläggning; strålterapi; operationsanalys; heltalsprogrammering; villkorsprogrammering; kolumngenerering; Optimeringslära och systemteori; Optimization and Systems Theory;

    Abstract : The manual scheduling of patients for radiation therapy is difficult and labor-intensive. With the increase in cancer patient numbers, efficient resource planning is an important tool to achieve short waiting times and equal right to care. This thesis studies an operations research approach to the radiation therapy scheduling problem.
