Classical Tunneling Function versus Exponential Tunneling Function in TunnelingAlgorithm

Global optimization is an active research area due to its ability to provide the bestset of parameters to optimize an objective function in the area of interest. Most of real lifeproblems are large-scale and nonlinear therefore it is felt necessary to find the global solutionfor large-scale and nonlinear optimization problems. Finding global minimizer of a functiondefined in an n-dimensional linear space is one of the most interesting areas in nonlinearprogramming. This paper considers the performance of the classical tunneling function incomparison with the exponential tunneling function in the tunneling algorithm. The proposedalgorithm is applied to multivariable and nonlinear functions. For both tunneling functions,the tunneling algorithm was able to find the global minimizer.
