- Gradient-free optimisation for the automatic suppression of instabilities
The recent advent of powerful algorithms able to extract information from large sets of data without the need of accurately modelling physical systems is having a large impact on the engineering world. Gradient-free methods, dynamic mode decomposition, clustering and genetic algorithms are examples of the tools that the combustion and acoustic communities are exploiting to shed new light on available data, or to solve optimisation problems that require a too large amount of computational power with standard methods.
