A filled function approach is proposed for solving a non-smooth unconstrained
global optimization problem. First, the definition of filled function in Zhang (2009) for smooth global
optimization is extended to non-smooth case and a new one is put forwarded. Then, a novel filled
function is proposed for non-smooth the global optimization and a corresponding non-smooth algorithm
based on the filled function is designed. At last, a numerical test is made. The computational results
demonstrate that the proposed approach is effcient and reliable.
