On implementing a linear programming algorithm in q

The goal of linear programming is to achieve the best possible outcome in a mathematical model consisting of linear equations. The earliest linear programming algorithms date back nearly 80 years, yet it still remains an active area of research to this day.

Many complex modern problems may be formulated in terms of linear programming, such as production cost minimization, transportation cost optimization, profit maximization and power flow optimization.

In this talk, we will discuss an implementation of a linear programming algorithm in q and show how it may be applied to minimize the cost of a power flow network for electricity system operators.

Insights into kdb+ 3.6

5 Jun 2018 | , ,

At Kx25, the international kdb+ user group conference held on May 18th, we released kdb+ version 3.6. With this release, we are opening up new possibilities for kdb+ application developers.
It provides a lot of new capabilities and streamlines previously complex processes so that programmers will be able to take a simpler approach to writing systems compared to what they did in the past.
