Adding RRPlugins (Loader) to LibRoadRunner

Finally, I finished removing 4412 bugs to 0 :D.  

I add a large codebase in roadrunner and I know there will be a lot of conflicts between them as they may do share common variables and similar files. I first started with modifying CMake files and then modified the source files such that there will be no conflict. But when I started building it is giving some error in windows files of windows software development kit which is strange since I am not using any system-dependent files. Then I found out that accidentally many variables between two projects get interlinked due to error-prone cmake lists. It was a hard time finding the bug. And there are no debuggers available for the build process so I have to go manually line by line and find out the problem. I wonder how patient developers from the nineties since at that there are no such high tech IDK and developers have to manually do most of the things. Anyway, I resolved the issue and will start my work with the wrapper part

Now my approach will work on
1. Wrapper  (Complete C API and then modify python API for rrplugins)
2. add_noise plugin (No roadrunner support required)
3. auto2000   (roadrunner support required)
4. Make any existing optimizer (nelder_mead) work (I want to work on an optimizer plugin so that I can use the code for differential evolution by changing the main algorithm)
5. Differential evolution. (Change algorithm in step 4). 

I still have around 2 months left in my internship and most likely to finish my work and publish a research paper along with my mentor on my work.

Monte Carlo Bootstrap

Image
 The main work of Monte Carlo is to " Get some confidence   estimates".   The Monte Carlo plugin is used to obtain estimates of the confidence limits for a model’s parameters. This is in the context where experimental data exists and a parameter minimization method, such as Levenberg-Marquardt or Nelder-Mead has already been used in order to find a parameter minimum. The Monte Carlo algorithm is used subsequently at this minimum and will give an estimate of parameter confidence limits corresponding to the variance in the original experimental data. The plugin has properties such as the size of the Monte Carlo population, minimization algorithm to use (e.g. Nelder-Mead or Levenberg-Marquardt), and on output, confidence limits for each involved parameter. With some past updates, Monte Carlo is not working mainly due to the modifications in rrplugins and change of python version from 2.x to 3.x. I have modified the wrapper to let it work. Majorly the problem was with the passing

Update old plugins to Work in the current system

Image
 I have updated all the plugins ( https://github.com/sys-bio/rrplugins/tree/master/plugins/released ) working in the old system. Mostly they are not working because of the wrapper. When we pass a python string to C through CPython we need to it the format ctypes.c_char_p(String.encode('utf-8')) where String is the "string" we need to pass. Currently, the optimizer is not working if we need to fit the data by skipping any species. It is the first bad design I have seen in rrplugins. Now I am trying to port all the plugins from the old system to the new system.  One of the optimization example where I have to fit rate K1 and K2 based on species S1, S2, and S3 is:  Model: antimony_str = """ J1: S1 -> S2; k1*S1 J2: S2 -> S3; k2*S2    S1 = 1; S2 = 0; S3 = 0;  k1 = 0; k2 = 0;  """ The exact fitted value is k1 =0.45 and k2=0.15.  My output comes out to be  ChiSquare =  1.6501935363049038 Reduced ChiSquare =  0.017555250386222382 k1

End of GSoC 2.0

    My second innings of Google Summer of Code comes to an end. I have learned a lot of things. There is still some work left which I will complete after my exams. The link to my summer internship report is https://gist.github.com/debashish05/e1ec288a81d77e0fe61cbf336d147109 . I have learned a lot of things from my mentors and develop an inclination towards research. Works Done during this period: 1) RRPlugins have been integrated with Libroadrunner. So we don't require a separate build for rrplugins. Earlier this task was achieved in my last year project. But the problem is the change in roadrunner will force the plugins to need to rebuild, which is not the case now. 2) Build time will reduce since the plugins and roadrunner are not interdependent. Updated all the plugins (https://github.com/sys-bio/rrplugins/tree/master/plugins/released), in the current system. Earlier these plugins were not working due to outdated wrapper and some minor bugs. 3) Updated Python wrapper for rrplug
