Approximate Solution for Barrier Option Pricing Using Adaptive Differential Evolution With Learning Parameter

Autor: Werry Febrianti, Kuntjoro Adji Sidarto, Novriana Sumarti

Publikováno v: Mendel, Vol 28, Iss 2 (2022)

Black-Scholes (BS) equations, which are in the form of stochastic partial differential equations, are fundamental equations in mathematical finance, especially in option pricing. Even though there exists an analytical solution to the standard form, t

An Approximate Optimization Method for Solving Stiff Ordinary Differential Equations With Combinational Mutation Strategy of Differential Evolution Algorithm

Autor: Werry Febrianti, Kuntjoro Adji Sidarto, Novriana Sumarti

Publikováno v: Mendel, Vol 28, Iss 2 (2022)

This paper examines the implementation of simple combination mutation of differential evolution algorithm for solving stiff ordinary differential equations. We use the weighted residual method with a series expansion to approximate the solutions of s

Solving Constrained Mean-Variance Portfolio Optimization Problems Using Spiral Optimization Algorithm

Autor: Werry Febrianti, Kuntjoro Adji Sidarto, Novriana Sumarti

Publikováno v: International Journal of Financial Studies, Vol 11, Iss 1, p 1 (2022)

Portfolio optimization is an activity for balancing return and risk. In this paper, we used mean-variance (M-V) portfolio models with buy-in threshold and cardinality constraints. This model can be formulated as a mixed integer nonlinear programming

Solving some ordinary differential equations numerically using differential evolution algorithm with a simple adaptive mutation scheme

Autor: Werry Febrianti, Kuntjoro Adji Sidarto, Novriana Sumarti

Publikováno v: INTERNATIONAL CONFERENCE ON MATHEMATICS, COMPUTATIONAL SCIENCES AND STATISTICS 2020.

Differential equations have been used to describe phenomena in many fields. However, not all of differential equations can be solved in analytic ways so there is some approach being made to solve them numerically. One of the approaches is using Fouri

Solving systems of ordinary differential equations using differential evolution algorithm with the best base vector of mutation scheme

Autor: Novriana Sumarti, Werry Febrianti, Kuntjoro Adji Sidarto

Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON MATHEMATICAL SCIENCES AND TECHNOLOGY 2020 (MATHTECH 2020): Sustainable Development of Mathematics & Mathematics in Sustainability Revolution.

A general algorithm is presented to approximately solve a great variety of systems of ordinary differential equations (ODEs) independent of their form, order, and given conditions. The systems of ODEs are formulated as optimization problem because it
