Getting Started with FFMPEG for Windows
Some pointers on how to get ffmpeg installed for use in Windows environments.
Hash Tables as a means of fast lookup in STL / C++.
Introduction In a previous life I was involved in the design of routing optimization software for the telecoms industry. Finding the least cost route for a traffic demand between communicating network sites necessitates a search for all the tariffs provided by all of the carriers.
A Recursive Algorithm to Find all Paths Between Two Given Nodes in C++ and C#
Problem Outline This I tackled previously when working on the design and implementation of routing optimization algorithms for telecommunications networks. Given that a wide area network with nodes and interconnecting links can be modelled as a graph with vertices and edges, the problem is to find all path combinations
