1. Alternative letter-case form of Lagrangian.

1. not comparableOf or relating to Joseph Louis Lagrange (Giuseppe Luigi Lagrangia).

   After studying a recursive formulation and the associated Bellman equation, in section 5.5 we analyze a Lagrangian formulation that provides useful insights about how Lagrange multipliers on transition laws relate to gradients of value functions.
