ABSTRACT
In this research, the development of a fast numerical method was performed in order to solve the Option Pricing
problems governed by the Black-Scholes equation using an accelerated genetic algorithm method.
Where the Black-Scholes equation is a well known partial differential equation in financial mathematics. A discussion of
the solutions was introduced for the linear Black-Scholes model with the European options (Call and Put) analytically and
numerically ,with and without transformation to heat equation .Comparisons of the presented approximation solutions of
these models with the exact solution were achieved.

1. INTRODUCTION
Many mathematical models have been proposed to describe the evolution of the value of financial derivatives.
Financial models were generally formulated in terms of stochastic differential equations, [1]. Linear Black-Scholes
equation the model was developed by Fischer Black and Myron Scholes [2], as an important equation in the financial
mathematics.

Where S:= S(t) > 0 and t є (0, T ), provides both the price for a European option and a hedging portfolio that
replicates the option assuming that, [4].
• The price of the asset price or underlying derivative S(t) follows a Geometric Brownian motion W(t), meaning that
S satisfies the following stochastic differential equation (SDE).
dS(t) = µS(t)dt + σS(t)dW(t).
• The trend or drift µ (measures the average rate of growth of the asset price), the volatility σ (measures the standard
deviation of the returns) and the riskless interest rate r are constant for 0 ≤ t ≤ T and no dividends are paid in that
time period.
Equation (1) can be transformed into the heat equation to find the price of the option analytically, [1]. In this
research, the application of the accelerated Genetic Algorithm method was taken into account to solve the linear
Black–Scholes model for European options. Studying (1) for an American options would be redundant, since the value of
an American options equals the value of a European options if no dividends are paid and the volatility is constant, [6], [7],
[8], [9], [10].
