A computational justice model for resources distribution in Ad Hoc Networks
We propose a computational justice model for resource distribution in ad hoc networks using socially inspired computing and agent-based modeling. Ad hoc networks are self-organizing systems in which there is no central ... -
A computational solution for the software refactoring problem: a formalism toward an optimization approach
Software Refactoring consists in reconstructing the code design of an object-oriented system without affecting the external functionality. Common refactoring tasks, in the initial steps, detect the source code ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería de Sistemas e Industrial. -
A computational solution for the software refactoring problem: from a formalism toward an optimization approach
Abstract: Software Refactoring consists in reconstructing the code design of an object- oriented system without affecting the external functionality. Common refactoring tasks, in the initial steps, detect the ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería de Sistemas e Industrial. -
A framework for interactive training of automatic image analysis models based on learned image representations, active learning, and visualization techniques
