The TTH escaping mechanism from rapid convergence causes its higher CPU time
. To illustrate the economic nature of this amount, the improvement rate indicator was defined as follows:
Allowing multiple processes to run concurrently in a system and share resources (e.g., CPU time
) is a recent architectural technique that improves resource utilization.
In Section 3.2, we investigate the robustness and efficiency of the method by studying the behavior of its error and CPU time
versus the parameters of the method.
Table 4 lists the numbers of selected features, the mean and standard deviation of both fitness values and CPU time
of GATS, GA, multistart TS, and ReliefF methods through 50 times runs.
where t is the CPU time
for the computation and the subscripts "POD" and "FDM" represent the results from the POD model and from the direct calculation of the governing equations via the FDM.
The numerics in Table 5 show that the prices obtained by NCIM and FDM benchmark are very close and the relative errors are less than 0.25% in most cases, whereas the CPU time
for NCIM is less than the FDM, and the reasons for NCIM achieving good performance have two aspects: on the one hand, the NCIM has the exponential-order convergence rate with respect to the number of the quadrature nodes L for the hyperbolic contour integral (see formula (83)); on the other hand, there is no iterative procedure for numerical finding the free-boundary value of the corresponding perpetual American volatility put; thus it is not like .
In Section 3, the use of essential systems to further reduce CPU time
The global time step method calculates the stable time step based on the full model, which often results in higher time step than the element or nodal-based time step." This change potentially reduces CPU time
from 24 percent to 48 percent.
Figure 7 compares the CPU time
required for finding optima with the three distinct CP models.
Further in Table 2, we compute the CPU time
for the computational of solutions for the test Problem 1.
The obtained results are shown in Figure 3, which reports the 2D cuts corresponding to the direction of maximum radiation for both synthesized patterns, and in Table 1, which reports the SLL referring to the entire angular domain [THETA], the maximum Axial Ratio (AR) in the 3 dB main lobe of each synthesized pattern, the DRR, and the CPU time
required for the synthesis.
Additional measures are the CPU time
. The required CPU time
is reported to indicate the usefulness of models MIP, RM-SPIP, and RM-DPIDP.
