  2. 2. Distributed Optimization with Nonconvexities and Limited Communication

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Sindri Magnússon; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Nonconvex Optimization; Wireless Sensor Networks; Cyberphysical Systems.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In economical and sustainable operation of cyber-physical systems, a number of entities need to often cooperate over a communication network to solve optimization problems. A challenging aspect in the design of robust distributed solution algorithms to these optimization problems is that as technology advances and the networks grow larger, the communication bandwidth used to coordinate the solution is limited.

  3. 3. Distributed Optimization in Time-Varying Environments

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Marie Maros; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Solving optimization problems in a distributed manner is critical in many systems. Many relevant systems are distributed in nature in the sense that they consist of autonomous agents that are to come to a joint decision based on a certain metric. LÄS MER

  4. 4. Asynchronous First-Order Algorithms for Large-Scale Optimization Analysis and Implementation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Arda Aytekin; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex; optimization; asynchronous; algorithms; parallel; distributed; large-scale; big data; software; serverless; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER

  5. 5. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Rasmus Bokrantz; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

    Sammanfattning : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. LÄS MER
