Abstract: While Metaheuristic optimization techniques are known to work well for clustering and large-scale numerical optimi-zation, algorithms in this category suffer from issues like reinforcement stagnation and poor late-stage refinement. In this paper, we propose the Improved Geyser-Inspired Optimization Algorithm (IGIOA), an enhancement of the Geyser-Inspired Optimization Algorithm (GIOA), which integrates two primary components: the Adaptive Turbulence Operator　(ATO) and the Dynamic Pressure Equilibrium Operator(DPEO). ATO allows IGIOA to periodically disrupt stagnation and explore different regions by using turbulence, while DPEO ensures refinement in later iterations by adaptively modulating convergence pressure. We implemented IGIOA on 23 benchmark functions with both unimodal and multimodal contours, in addition to eight problems pertaining to cluster analysis at the UCI. IGIOA, out of all the tested methods, was able to converge most accurately while also achieving a stable convergence rate. The mitigation of premature convergence and low-level exploitation was made possible by the turbulence and pressure-based refinements. The findings from the tests confirm that the adaptation of baseline strategies by IGIOA helps deal with complex data distributions more effectively.　However, additional hyperparameters which add complexity are introduced, along with increased computational cost.　These include automatic tuning of parameters, ensemble or parallel variations, and hybridization with dedicated local search strategies to extend the reach of IGIOA for general optimization while also specializing it for clustering focused
