GSoC'15 Idea: Approximation with Parametric Splines
by Anastasiia Tsyplia April 4, 2015

April 4, 2015

Hello, My name is Anastasiia Tsyplia. I am a 5th-yaer student of National Mining University of Ukraine. I am keen on interpolation/approximation with splines and it was a nice surprise to find out that there is a demand in interpolation improvements amongst the Scipy's ideas for GSoC'15. However, I've spend some time on working out the idea <https://drive.google.com/file/d/0BzveGSDwNVtBanU1THpFTXNKZHc/view?usp=shari…> of my own. Recently I've made a post <http://tsplb.blogspot.com/> dedicated to description of the parametric spline curves construction process and approaches to approximate engineering data by spline functions and parametric spline curves with SciPy. It seems that using parametric spline curves in approximation can be extremely useful and time-saving approach. That's why I would like to share my project idea and hope to hear some feedback as I am about to make a proposal for the Google Summer of Code. I have a 2-year experience in programming with Python, PyOpengl, PyQt, Matplotlib, Numpy & SciPy. Some time I spent to dive into ctypes and scratched the surface of C. Now my priority is Cython. I've read the book on the spline methods recommended on SciPy's idea page, so I feel myself competent in spline methods. I feel free with recursions: the last challenge I faced was implementation of binary space partitioning algorithm in python as I was writing my own ray-tracer. I would like to contribute to SciPy by any means, so I'm ready to receive instructions on my next move. And, certainly I'm looking forward to start dealing with B-Splines in Cython as it is also a part of my project idea. Thanks in advance, Looking forward to receive the feedback, Anastasiia Tsyplia

Github code for Differential Evolution reevaluations
by James Phillips April 3, 2015

April 3, 2015

I have just reviewed the Differential Evolution code in github. It is is particularly well coded and most algorithmically thorough, my professional compliments. I noticed in the older DE code I use there is a possible performance improvement, and this seems to be the case in the github code as well. Not every population vector changes within a generation, yet my older code reevaluates the unchanged vectors. Of course this does not change the final results, but is a point of potential savings in total computation time. Respectfully, James Phillips
