In this article, we approach the problem ( 1.3) from a different perspective, by utilizing the weak form of the differential equation. Recall that for any smooth test function ϕ:R→R (absolutely continuous is enough) and interval (a,b)⊂[0,T], equation ( 1.1) admits the weak formulation.

WebSymINDy is a new algorithm for the reconstruction of non-linear dynamics. It uses symbolic regression and SINDy algorithm to recover the systems of equations from time-series observations. It is free from the linearity assumption and thus is able to reconstruct systems unreachable for SINDy.
