CXXGraph
A header-only C++ library for graph representation and algorithms, designed as a modern alternative to Boost Graph Library.
What is CXXGraph?
CXXGraph is a header-only C++ library for graph representation and algorithms. It provides a comprehensive set of graph data structures and algorithms, such as shortest path, traversal, and network flow, designed to be a modern, easier-to-use alternative to the Boost Graph Library.
C++ developers working on projects that require graph algorithms, such as network analysis, pathfinding, dependency resolution, or data structure implementations.
Developers choose CXXGraph for its minimal boilerplate, readable API, and fast setup compared to Boost Graph Library, while offering a wide range of algorithms and modern C++17 compliance.
Overview
Header-Only C++ Library for Graph Representation and Algorithms
Use Cases
Best For
- Implementing graph algorithms in C++ without heavy dependencies
- Educational projects teaching graph theory and algorithm implementation
- Network analysis and pathfinding applications
- Dependency resolution and topological sorting in build systems or schedulers
- Prototyping graph-based features with minimal setup time
- Projects requiring a lightweight, header-only graph library
Not Ideal For
- Projects requiring high-performance distributed graph processing on clusters, as CXXGraph focuses on single-machine algorithms despite having partitioning features.
- Teams with extensive existing codebases built on Boost Graph Library, where migration effort outweighs benefits due to API differences.
- Applications needing real-time graph updates with sub-millisecond latency, as performance optimizations for dynamic graphs are not highlighted.
- Environments constrained to C++14 or earlier standards, since CXXGraph mandates C++17 compliance.
Pros & Cons
Pros
Just include CXXGraph.hpp for integration without separate compilation, reducing setup time to seconds compared to Boost's minutes-hours.
Implements over 20 algorithms including Dijkstra's, BFS, DFS, and network dynamics matrices, covering most common graph needs out of the box.
Leverages contemporary C++ features for safety and expressiveness, ensuring code is up-to-date and less error-prone.
Designed with a clean, readable API that significantly reduces verbose code compared to Boost Graph Library, as shown in the comparison table.
Cons
Unit tests and benchmarks require separate installations of GoogleTest and Google Benchmark, adding setup complexity beyond the core library.
As a newer project, it has a smaller community and fewer third-party integrations compared to established libraries like Boost, which may affect long-term support.
While benchmark results are provided, the library may not be optimized for all graph scales or types, especially for massive or highly dynamic graphs.
