Graph-Theoretic Approaches for Optimizing Communication Networks: A Study of Shortest Path and Minimum Spanning Tree Algorithms

with Alok Kumar Saini

08 Sep 2026 • Volume 10, Issue 1 • pp. 28-38

The exponential growth of digital communication systems has increased the complexity of network infrastructures across telecommunications, internet services, transportation systems, cloud computing environments, and wireless sensor networks. Efficient management and optimization of these networks have become critica...

Accuracy and Discrete Energy Behaviour of L1 and L2-1? Time-Stepping Schemes for Caputo Fractional Diffusion Equations

with Jinage Sanjeevkumar Shivshankar

03 Jun 2026 • Volume 12, Issue 6 • pp. 1-9

Time-fractional diffusion equations combine a nonlocal memory operator with diffusion and therefore require time-stepping methods that are accurate without losing the qualitative stability of the underlying problem. This paper provides a controlled computational comparison of the classical L1 formula and the second-...

Stability, Convergence and Error Analysis of An Adaptive Modified Euler Method for Nonlinear Ordinary Differential Equations

with Tiwari Nagesh Govindram

03 Jun 2026 • Volume 12, Issue 6 • pp. 10-16

This paper examines the consistency, convergence, error propagation and absolute stability of a step-doubling adaptive modified Euler method for nonlinear initial value problems. The underlying Heun update has a second-order Taylor expansion and a cubic local defect. Two half steps retain second-order global converg...
