    abstract = {In this study, an analytical expression for the solution of the ratio-dependent 
  predator-prey system with constant effort harvesting by an adaptation of the 
  Homotopy Perturbation Method (HPM) is presented. The HPM is treated as an algorithm 
  for approximating the solution of the problem in a sequence of time intervals, 
  i.e., HPM is converted into a Hybrid Numeric-Analytic Method. Residual error 
  for the solution is presented.}
