In this work, we present both the Forward-in-Time and Backward-in-Time Monte Carlo solutions. We present an implementation of both algorithms in the framework of HelMod Code showing that the difference between the two approach is below 5\\% that can be quoted as the systematic uncertain of...
Despite these flaws, reading the code with these names I can at least understand that the incoming samples are expected to be constrained (thus the application of theunconstrainmethod). The jittering is happening in the unconstrained space (that makes sense) then the samples are sent back to t...

solution to the midpoint of the time step using the traditional small step splitting method, the advection tendencies are then recomputed at the midpoint of the time step, and the solution is restarted at time t and advanced to t,,t using the KW78 small step method.WS98 showed that ...
Based on the time-varying basis function expans io n theory, a new method combining forward and backward linear prediction of non-s tationary signals is presented to estimate TVAR parameters. Computer simulation shows that the method can solve the one-step delay problem and overcome the comp uti...
The results differ from backward integration because the Euler method is not symmetric with respect to the evolution of time. Nevertheless, first-order forward and backward integration are both first-order approximations of the true solutions, and forward mapping is an acceptable approximation to the ...
Table 5 presents a comprehensive comparison of time complexities (in minutes and seconds) among various learning strategies, including our proposed method, Forward-backward21, Modified Greedy Layer-Wise23, End-to-End (Cross Entropy - SGD), and End-to-End (Cross Entropy - Adam), applied to the...
Fourthly and a priori most surprisingly, our -lemma moves the given disk transversal to the unstable manifold backward in time, although there is no backward flow. As a first application we propose a new method to calculate the Conley homotopy index of x....
