On optimization, control, and the systems that learn to steer themselves — a working record of ideas, projects, and ventures.
In the beginning was the problem, and the problem was ill-posed, and the problem was constrained. Without a good objective function, nothing worth optimizing was made.
Uviwe Jumba is a mathematician and computer scientist working at the intersection of optimization, control, and machine learning — drawn to the question of how a system, given a goal and a set of limits, finds its way to the best available answer.
A graduate of Rhodes University, where he read for a BSc in Applied Mathematics and Computer Science, Uviwe's interest runs from the classical machinery of optimization and control theory through to the broader, faster-moving world of machine learning and artificial intelligence — with a growing focus on where the two meet: systems that don't just predict, but decide.
Outside the theory, that same instinct — take a hard, constrained problem and build something that actually works — is what led to founding Nabla Dynamics, and to the projects gathered here.
A library of South African Olympiad solutions
Every problem the South African Mathematical Olympiad has set, worked from first principles and typeset the way a proof deserves. A growing, open archive for anyone still awake at midnight with a blank page and a hard problem — the way its author once was.
Enter the archive →Numerical & computational engines
Nabla Dynamics builds sophisticated numerical and computational engines designed to solve complex, real-world problems across diverse domains — infrastructure engineered to disappear into the products it powers.
