The soundness of the encoding is derived from the soundness of a goal directed sequent calculus designed for eBBI.
The advocated approach is the direct method of calculus of variations based on inverse dynamics in the virtual domain.
Then, by the direct method in calculus of variations, I is bounded from below and attains its infimum at some x ∈ X, which, by virtue of ([20], Proposition 1.1) and Proposition 2.1, is a solution of problem (1.1), (1.2).
Anyway, it is important to note that an easy use of the Direct Method of Calculus of Variations (i.e. taking a minimizing sequence, saying that it is compact in some topology—here it is the weak convergence of probability measures finding a limit, and proving semicontinuity, or continuity, of the functional we minimize, so that the limit is a minimizer) proves that a minimum does exist.
Calculus wasn't measured in this study as it isn't considered the primary aetiological factor in periodontitis [ 16] so a direct comparison of calculus build up and disease progression cannot be made.

We notice that the existence of solutions for fractional finite difference equations is a hot topic of the fractional calculus with direct implications in modeling of some real world phenomena which have only discrete behaviors.
Hence, by applying the direct method in the calculus of variations, the minimum problem (2.23) admits a unique solution (bar{w}) which is the optimal control of problem (2.24) with respect to the cost functional (3.18).
