Abstract: In this paper we propose an optimized algorithm, which is faster compared to previously described Modified Super-Time-Stepping (Modified STS) scheme for age-structured population models with diffusion. Keeping the accuracy of the Modified STS algorithm, we reduce its computational time almost two times, obtaining an additional speed-up. This makes the optimized method highly preferable for nonlinear and higher-dimensional problems. *2000 Mathematics Subject Classification: 35M10, 65N06, 65N12, 92B99.
Description: Дойчин Бояджиев, Галена Пеловска - В статията се предлага оптимизиран алгоритъм, който е по-бърз в сравнение с по- рано описаната ускорена (модифицирана STS) диференчна схема за възрастово структуриран популационен модел с дифузия. Запазвайки апроксимацията на модифицирания STS алгоритъм, изчислителното времето се намаля почти два пъти. Това прави оптимизирания метод по-предпочитан за задачи с нелинейност или с по-висока размерност.
