From this point of view a curve or a surface can be identified with a linear functional over the class of variational integrands. |
It was one of the earliest variational problems and its investigation was the starting point for the development of the calculus of variations. |
Problems remained, however, which Kirchhoff solved using variational calculus. |
Celestial mechanics is the origin of dynamical systems, linear algebra, topology, variational calculus and symplectic geometry. |
This paper proposes a novel probabilistic variational method with deterministic annealing for the maximum a posteriori estimation of complex stochastic systems. |
Regarding complexity pertaining to the variational approach, Ref. describes a little complexional overhead. |
