For enlarging the convergence region of the Picard iteration method, multistage algorithm is devised. We also introduce an algorithm for problems with some singularities at the limits of integration including fractional integral equations. Numerical tests verify the validity of the proposed schemes. %K Volterra Integral Equation %K Picard Iteration Method %K Numerical Integration %K Multistage Scheme %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=59419
