Incremental treatments of the full configuration interaction problem

The recent many-body expanded full configuration interaction (MBE-FCI) method is reviewed by critically assessing its advantages and drawbacks in the context of contemporary near-exact electronic structure theory. Besides providing a succinct summary history MBE-FCI to date within generalized unified theoretical setting, finer algorithmic details are discussed alongside our optimized computational implementation A selected few most applications revisited, before we close outlining future research directions as well place among modern wave function-based methods.
