The original serial implementation of the segmentation algorithm exhibits suboptimal performance, motivating a systematic optimization effort without compromising accuracy.To analyze the unoptimized serial code and apply iterative code and compiler optimizations while preserving segmentation accuracy.A multi‐stage optimization process was employed: Initial algorithm profiling to identify bottlenecks. Iterative application of static code transformations. Integration of compiler‐level optimizations at each stage.Performance testing demonstrates substantial speedups: 6x to 8x improvement over the original implementation, depending on optimization stage. Parallelization in the final step further enhances throughput without sacrificing correctness.Systematic, profile‐guided optimization by combining code refactoring and compiler tuning yields significant performance gains. The approach maintains accuracy while enabling efficient parallelization, offering a scalable template for optimizing similar compute‐intensive algorithms.

This study deals with the unfolded quantities based on the time intervals between successive neutron events from the aspect of the power law. Neutrons from spontaneous fission in special nuclear material induce fission in most cases. In this study, it was demonstrated that the inverse value of the number of induced neutrons decreases following a power function with the increasing radius of a plutonium metal sphere. In addition, it was considered an increase in the neutron background level with increasing altitudes. The inverse value of the mean neutron counting rate depending on altitudes can be described with a power function merely for higher elevations. A linear relationship was obtained by plotting the quantities on logarithmic axes against each other indicating generally a power law relationship for both investigated phenomena. The results of this study showed a connection between two seemingly unrelated neutron phenomena through power laws based on the distributions of time intervals between successive neutron counts. The empirical evidence implies that a connection between the observed quantities in a log-log plot is unchanged except for a multiplicative constant.
