The study proposes an improved Harris hawks optimization(IHHO) algorithm by integrating the standard Harris hawks optimization(HHO) algorithm and mutation-based search mechanism for developing a high-performance machine learning solution for predicting soil compression index. HHO is a newly introduced meta-heuristic optimization algorithm(MOA) used to solve continuous search *** to the original HHO, the proposed IHHO can evade trapping in local optima, which in turn raises the search capabilities and enhances the search mechanism relying on mutation. Subsequently, a novel meta-heuristic-based soft computing technique called ELM-IHHO was established by integrating IHHO and extreme learning machine(ELM) to estimate soil compression index. A sum of 688 consolidation test data was collected for this purpose from an ongoing dedicated freight corridor railway project. To evaluate the generalization capability of the proposed ELM-IHHO model, a detailed comparison between ELM-IHHO and other well-established MOAs, such as particle swarm optimization,genetic algorithm, and biogeography-based optimization integrated with ELM, was performed. Based on the outcomes, the ELM-IHHO model exhibits superior performance over the other MOAs in predicting soil compression index.

This paper proposes an improved football team training algorithm(IFTTA), which integrates chaotic mapping and an opposition-based learning(OBL) strategy, addressing the deficiencies of the conventional algorithm such as sluggish earlystage convergence and susceptibility to local optima. Firstly, we propose a novel chaotic mapping technique, termed the iterative logistic-skew-tent map with infinite collapses(ILSTMIC), which exhibits robust chaotic characteristics. This mapping method is then utilized to optimize the initialization phase of the football team training algorithm(FTTA), significantly enhancing its early-stage convergence rate. Moreover, drawing parallels to the collaborative training practices among top-performing students in Chinese high schools, this paper incorporates a joint training phase into the FTTA based on the OBL approach, thereby augmenting its global optimization capabilities. The efficacy of the proposed IFTTA is validated against the CEC2022 benchmark,where it is compared with other leading optimization *** findings demonstrate that the IFTTA outperforms these algorithms in terms of both convergence speed and accuracy.
