    Existing bio-inspired models are challenged with premature convergence among others.In this paper,an adaptive social spider colony optimization model based on the foraging behaviour of social spider was proposed as an optimisation problem. The algorithm mimics the prey capture behaviour of the social spider in which, the spider senses the presence of the prey through vibrations transmitted along the web thread. Spiders are the search agents while the web is the search space of the optimization problem.The natural or biological phenomenon of vibration was modeled using wave theory while optimization theory was considered in optimizing the objective function of the optimisation problem. This objective function was considered to be the frequency of vibration of the spiders and the prey as this is the function that enables the spider differentiates the vibration of the prey from that of neighbouring spider sand therefore forages maximally. To address the parameter tuning problem, the searchpatternwascontrolledbythepositionofthepreyforconvergence.The proposed model was tested for convergence using several benchmark functions with different characteristics to evaluate its performance and results compared to an existing state of the arts’ spider algorithm. Results showed that the proposed model performed better by searching the optimum solution of the benchmark functions used to test the model
