3rd and 4th Week

–

After completing fixed order variable step size multistep methods, I started working on variable order variable step size Adams Moulton method. This method is given in [1]. It is a predictor-corrector method. When debugging I was stuck at error estimation part, and Chris helped me a lot in resolving the issue. Though I have completed algorithm, I will be working on optimisation and possible changes to improve the performance of the method.
