This paper specifically develops a computational approach in estimating the amount of pond pollution and determining the long time(every 48 hours) behavioural representation of the pond pollution model.This approach, which can be considered as an extension of the block predictor-corrector methods in form of implicit block multistep method has many computational advantages usingvariable step size technique. Moreover, it possesses some important advantages of designing a suitable step size, stopping criteria(prescribed tolerance level) and error control/minimization as well. This makes the new approach specifically efficient for solving systems of first-order ordinary differentialequations. Analysis of some theoretical properties of the method is carried out to ascertain the extent of performance of the method.

Abstract-Appraising computed error in forecasting-adjusting system is all essential for purposeful acquiring suited pace size. Diverse schemata for controlling/estimating error bank on forecasting-adjusting system. This study examines multiprocessing suited pace size (adaptive) proficiency for ciphering first order ordinary differential equations (ODEs).
