The algorithm is a combination of an explicit block that solves the non-stiff part and an implicit block that solves the stiff part of the problem.
The explicit block is always solved inside the implicit block as part of the nonlinear function evaluation making use of the Jacobian-Free Newton Krylov (JFNK) method (Knoll and Keyes, 2004; Nourgaliev et al., 2010; Saad, 2003).
In this way, there is a continuous interaction between the implicit and explicit blocks meaning that the improved solutions (in terms of the time accuracy) at each nonlinear iteration are immediately felt by the explicit block and the improved explicit solutions are readily available to form the next set of nonlinear residuals.

We note that the classic IMEX methods split the operators such a way that the implicit and explicit blocks are executed independent of each other, and this may lead to non-converged nonlinearities therefore time inaccuracies for certain models.
Subject- and condition-wise averages were calculated for the eight conditions blocked explicit negative, blocked explicit positive, blocked assigned negative, blocked assigned positive, mixed explicit negative, mixed explicit positive, mixed assigned negative, and mixed assigned positive.
The eight feedback conditions were evenly distributed across participants (blocked explicit negative: 12.7%, blocked explicit positive: 12.3%, blocked assigned negative: 13.0%, blocked assigned positive: 12.0%, mixed explicit negative: 12.8%, mixed explicit positive: 12.2%, mixed assigned negative: 12.8%, and mixed assigned positive: 12.2%).
Last year, Beaver College in Glenside, Pa., decided to change its name to Arcadia University, in part because some filters intended to screen out sexually explicit material blocked access to its site.
The move follows the 22 July announcement from Prime Minister David Cameron that most households would have sexually explicit material blocked by the internet provider unless they chose to opt out.
Furthermore, the data suggest that eye movement patterns did not differ between extrapolated and explicit task blocks.
Although they have no explicit authority to block a new reactor, local officials can withhold permits to use the water from a river for cooling, for example, or refuse to co-operate on emergency planning.
This little-known law is significant because Congress crafted it, in part, with the explicit intent to block the U.S. from buying Canadian tar sands oil -- considered the dirtiest oil on the planet.
