Abstract: An increasing demand for large scale inverse problems in many application domains (for example, seismic inversion, electromagnetic geophysical surveying, and novel high-resolution medical imaging technologies) has driven a significant growth in research efforts in the field of computational inverse problems. New methodologies have been developed to address scalability and robustness issues for large scale problems. Examples include multilevel strategies, adaptivity, and preconditioning. Also, a problem-specific development of efficient, tightly-coupled forward and inverse solvers often leads to successful methods for large scale applications. The aim of this minisymposium is to present recent trends in this field and provide a forum for exchange and discussion.
