Constructing numerically stable real number codes using evolutionary computation

2010 
Real number codes have been widely used in many applications. However, it is difficult to analytically find the numerically optimal codes even for three erasures. In this paper, an evolutionary computation approach is presented which can computationally construct real number codes that have near optimal numerical stability. Experimental results demonstrate that the evolutionary algorithm presented here produces real number codes close to the theoretical optimum for two erasures. The real number codes obtained from the evolutionary algorithm outperform any known existing real number codes for three erasures.
