Query: 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 of the history of MBE-FCI to date within a generalized and
unified theoretical setting, its finer algorithmic details are discussed
alongside our optimized computational implementation of the theory. A selected
few of the most recent applications of MBE-FCI are revisited, before we close
by outlining its future research directions as well as its place among modern
near-exact wave function-based methods.
