A METHOD FOR SOLVING EXTREMAL PROBLEMS IN ALGEBRA AND STEREOMETRY
In this article, we propose a method for solving extremal problems in algebra and stereometry. The method is applied to problems that can be addressed using basic elementary inequalities and trigonometric equalities in triangles. These problems are reduced...

FAST ADAPTIVE ENTROPY-DRIVEN MULTILEVEL IMAGE SEGMENTATION USING LOOK-UP TABLES ON GPU PLATFORMS
This paper proposes a fast, adaptive method for multilevel image segmentation based on Kapur’s entropy. Implemented on CPU and GPU, the method achieves up to 40× acceleration using CUDA and memory optimization. Segmentation quality is preserved while enabling...
