The multiple requirements placed on modern real-world processes and systems are ever more demanding. Meeting such requirements can only be achieved through systematic methods capable of identifying the best course(s) of action among the possible alternatives, which are generally known as optimisation algorithms. Optimisation algorithms find application in virtually all areas of knowledge and human activity, but require suitable models of the problems of interest in order to operate. Producing such models is often a challenging task which involves understanding both the problem at hand and the type of optimisation algorithm to be used, and may entail significant effort. Compared to their deterministic counterparts, Randomised Optimisation Algorithms (ROAs) tend to be simpler to design and implement while offering improved performance, particularly on large problems whose internal structure is not sufficiently well known or even available. However, ROAs are still far from reaching the level of widespread and systematic adoption enjoyed by more traditional optimisation solvers in the real world.
ROAR-NET aims at making randomised optimisation algorithms widely competitive in practice by identifying and reducing obstacles to their adoption at the scientific, technical, economic, and human levels. It focuses on meeting the needs of practitioners, from whose activities the economic value of optimisation solvers stems. These needs are taken as the driving force for new theoretical, methodological, and technical advances leading to the sustainable development of widely available software tools, training materials and programmes, and ultimately to more extensive acceptance and deployment of these methods.
The network brings together an extensive number of ROA theoreticians and algorithm developers, applied researchers, software developers, and practitioners, distributed across more than 40 countries. This geographical diversity assists in ensuring that the frameworks, libraries and software tools developed through the network are applicable to a wide range of real-world problem scenarios while supporting the latest theoretical developments.
