The phrase 'significant computational cost' is correct and can be used in written English.
It is often used to refer to the amount of time and/or resources that are required to process a given data set or operation. For example, "The company decided that the significant computational cost of running the simulation outweighed the potential benefits."
The GPR method provides high-quality meshes but requires significant computational cost.
Clearly, the proposed approach offers a significant computational cost reduction with respect to the chirp beamformer.
As mentioned above, the implementation of the joint MMSE estimator embeds a significant computational cost.
The proposed algorithm improved from original differential evolution (DE) is performed to reduce significant computational cost.
However, they are data intensive and have a significant computational cost.
The results show significant computational cost improvements compared to traditional combined plant/control optimization.
This behaviour would be considered boundedly rational if the costs of computing an acceptable boundary configuration were to increase with the level of accuracy required, because it would then be appropriate to tolerate small inequalities in district populations to save significant computational costs.
The response of model performance to grid size was non-linear and while the smaller grid sizes (⩽120 m) improved the hydrodynamic model results, these offered only slight improvements at very significant computational costs compared to grid size of 120 m, with grid sizes 250 m and greater decreasing in model accuracy.
The proposed double scale analysis yields accurate results with a significant reduced computational cost.
Uncertainty quantification (UQ) for CFD-based ship design can require a large number of simulations, resulting in significant overall computational cost.
Previous research has shown that force-based frame elements are superior to classical displacement-based elements enabling, at no significant additional computational costs, a drastic reduction in the number of elements required for a given level of accuracy in the simulated response.
