    Abstract: Teff is one of the most grown crops and a preferable food in Ethiopia. Wholesale prices for Teff are relatively high, making the crop attractive to some producers as a cash crop, production costs are also high, implying fertilizer prices and the labor-intensive nature of the crop. Now a daysteff got attention of international market. But, productiv... Show More

    Abstract: The traditional back-propagation neural network (BP) have the disadvantages including the random generation of initial weights and thresholds, easy to fall into the local optimization, and the convergence speed is slow, and it’s hard to confirm the number of neurons in hidden layer. In this paper, the Genetic Algorithm (GA) is utilized to optimize ... Show More
