Deswik Pseudoflow Explained: A Modern Approach to Pit Optimization
By Deswik
This whitepaper offers a detailed comparison between Deswik’s Pseudoflow pit optimization algorithm and the industry-standard Lerchs-Grossman (LG) method used in Whittle software.
Authored by former Deswik employee and mining engineer Julian Poniewierski, it explores the evolution of optimization techniques, highlighting the computational efficiency and flexibility of the Pseudoflow algorithm. With practical insights into setup, block model regularization, and common modeling pitfalls, the paper positions Deswik’s solution as a robust alternative for modern open pit design.
