*3.8.3 Merits*

A meta-heuristic method exhibits several advantages as easier for applications to change parameters to meet requirement of applications. It is very easy fall for optima of local solution to slow convergence rate. In addition, cuckoo search is simple and easy to follow with real-world engineering applications. Cuckoo search algorithm easy to implement in comparison to other population algorithms.

### *3.8.4 Demerit*

CSA is about easy to fall into local optima solution due to its simplicity. Slow the convergence rate randomness is still a problem. Self-adaptability may be limitation under certain problems. Low efficiency, less accuracy can be experienced while dealing with multi-peak function.
