The phrase "a existing approach" is not correct.
It should be "an existing approach." You can use the corrected phrase when referring to a method or strategy that is currently in use or recognized.
Example: "The researchers decided to build upon an existing approach to improve the efficiency of the process."
Alternatives: "a current approach" or "a prevailing approach."
The first one, weighted lookahead, is a variant of an existing approach by Shimbo and Ishida, and utilizes the weight while the algorithm performs lookahead search.
Under an existing approach, an unknown input observer is designed in deterministic context.
On the positive side, we find an exact solution technique for general SGPs based on an existing approach, and develop a PTAS (polynomial-time approximation scheme) for zero-sum SGP to more fundamentally overcome the computational obstacle.
In this paper, we propose an alternate approach to an existing approach that handles the sum of distance-weighted closeness relationships and distance-weighted interactions assigned relative weights in the objective function.
In this approach, you disagree with an existing approach to an issue or field of study and put forward your conflicting approach, theory or claim.
However, at this moment we chose to rely on an existing approach that retrieves a set of events that are comprehensive and cohesive enough to test our system.
The checklist helps those seeking to undertake a health research priority setting exercise to make an informed choice as to which comprehensive approach to use or provides assistance for creating a high quality priority setting process without use of an existing approach.
Here, we describe such a policy model ("Buying Green Cover") and compare it with an existing approach, the GGP, using data from China's Northern Shaanxi Province.
In this paper, we first explore an existing approach based on vocal tract length perturbation and we propose a different DA technique based on feature perturbation to create a modified training data sets.
To compare our method with an existing approach for unsupervised data integration, we apply MDI to an example previously considered by Savage et al. (2010) in the context of transcriptional module discovery.
