The phrase "a problem originally" is correct and usable in written English.
It can be used when discussing the initial nature or source of a problem in a context where you are explaining its origins or background.
Example: "The project faced a setback due to a problem originally identified during the planning phase."
Alternatives: "an issue initially" or "a challenge at first".
We are looking for a steady-state solution of an external flow problem originally formulated on an unbounded domain.
In his paper, he discussed as an example the Apollonius problem originally posed by Apollonius of Perga during the Hellenistic period; the method of constructing a circle tangent to three given circles.
Minimum relative entropy (MRE) and Tikhonov regularization (TR) were compared by Neupauer et al. [Water Resour. Res. 36 (2000 2469]] on the basis of an example plume source reconstruction problem originally proposed by Skaggs and Kabala [Water Resour. Res. 30 (1994) 71] and a boxcar-like function.
Jasra et al. (2005) favoured a third approach to the label-switching problem, originally proposed by Celeux et al. (2000) and Hurn et al. (2003).
In this note we provide a concise report on the complexity of the causal ordering problem, originally introduced by Simon to reason about causal dependencies implicit in systems of mathematical equations.
The relativistic version of the magnetic rotor problem, originally proposed by Balsara and Spicer (1999), has by now become a standard numerical test in RMHD.
The point is, if this is permitted, then there is no limit to the ability to extend terms, and that is precisely contrary to what the framers had in mind when they worried about this problem originally.
In this problem, originally introduced in [6], there are two types of processes: reader processes and writer processes.
The vehicle routing problem originally belonged to the NP-hard combinatorial optimization problem, thus its variants with more indices and constraints, undoubtedly, would be NP-hard as well.
We propose improvements to some of the best heuristic algorithms for optimal product pricing problem originally designed by Dobson and Kalish in the late 1980s and in the early 1990s.
