[R] Seeking implementation of my algorithm 'spdspds' - a novel algorithm for solving Linear Programming Problems with O(L^1.5) computational complexity
Friends: i am a retired Professor - not having any access to the resources (human/financial/business/whatever) that may be required - therefore i am seeking implementation of my algorithm 'spdspds' - a novel algorithm for solving Linear Programming Problems with O(L^1.5) computational complexity - in order to show/convince the esteemed world optimization community that it is indeed a great grand breakthrough in terms of achievement of the linear programming performance challenge of the millennium - with far reaching deep impact on optimization algorithm development in general - holy grail fantasy realized! I need some individual or team who is interested & willing to work on this. Earlier experience in implementation of optimization/LP algorithms will greatly help. You may access / download / read my paper - "Unbelievable *O*(*L*^1.5) worst case computational complexity achieved by spdspds algorithm for linear programming problem" which is available at - arxiv . org / abs / 1405 . 6902 Thanks a lot. - Dr(Prof) Keshava Prasad Halemane [[alternative HTML version deleted]]

Your best chance to get some interest is to adapt an existing package such as linprog or lpSolve to use your algorithm. Then there will be sufficient structure to allow R users and developers to see your ideas working, even if they are not efficiently programmed. It's always easier to start with something that is working and improve it. And you would be able to show comparisons of the existing examples by the current and new methods. I've worked on a lot of optimization (mainly function minimization) methods over many decades, and there are several "brilliant" ideas that have not turned out to be very good practical methods, while some rather pedestrian ideas have proved reliable and effective, even if they don't fulfill nice theoretical properties. There are, however, a few nice cases where theory and practice are both great.

" not having any access to the resources " You have internet (as is proven by sending this email) you even have R cli these days on mobile (I do anyway).

> solving Linear Programming Problems with O(L^1.5) > computational complexityI'm not an expert on this topic. However, a quick glance at the topic suggests that these sorts of algorithms are usually exponential in "n", here the number of variables/dimensions. Apparently, "L" is the number of input bits. Your notation suggests your algorithm is dependent on the number input bits only, and is otherwise constant in the number of variables/dimensions. So, we can solve an LP with hundreds of millions of variables, near-instantaneously...?
