Abstract
We present recent methodological developments in the context of three closely related computational optimization projects:
- The BARON project for algebraic optimization through a spatial branch-and-bound algorithm that exploits various convexification techniques.
- The ALAMO project, which relies on algebraic global optimization (BARON) to build simple models from data while enforcing shape constraints.
- The BAM project for data-driven optimization through the integration of sampling, partitioning, and global optimization (BARON) of local algebraic surrogates constructed from data (ALAMO).
We discuss connections between the three projects, report on the status of each project and their integration, and present computations on established benchmarks and applications.
