Algorithm Study provides tools and resources to augment the traditional study of algorithms. It includes implementations of common and less-common algorithms in a variety of languages and visualization tools to help in gaining a deeper understanding of the algorithms. The algorithm implementations are each accompanied by a discussion of the asymptotic ("big O") run time and memory limits of the algorithm. Some implementations include discussion of how the algorithm or data structure is commonly used and comparisons with similar algorithms or data structures. All implementations have test cases that exercise their functionality. The visualization tool, Algorithm Visualizer, displays what happens as various algorithms do their work.
swampex (or Swamp Explorer) is a cross-platform library designed to work with raster maps in Ozi Explorer format. Using this library, you'll be able to collect maps in the file system, get information about map calibration, find maps by latitude/longitude, render maps in SDL surfaces, and more.
libpersist is a small library of C++ base classes and templates providing the capability to store and load objects in their entirety across executions. It also provides for object relocation between threads in a NUMA (non-uniform memory access) parallel processing environment. Objects are stored to disk as POD. They are reconstructed when reloaded into memory. Relocation is a special case of persistence, requiring reconstruction after the POD has been moved in memory. After all objects have been relocated, all references to the objects are swizzled (their IDs are resolved to their addresses), so that they can be dereferenced efficiently.
HeeksCNC is a CAM (Computer Aided Manufacturing) add-on module for HeeksCAD. The user can add machining operations. These can then be output to NC code. The NC code is then shown as red and green lines on the screen. The NC code is generated using Python script, so it can be configured for different machines. HeeksCNC uses pycam for the "Zig Zag" operation, libarea for the "Pocket" operation, and libactp for the "Adaptive Roughing" operation.
Z88 is a fast, powerful, and compact finite elements analysis program. Z88 features 20 finite element types; it covers plane stress, plate bending, axial symmetric structures, and spacial structures up to 20-node Serendipity hexahedrons. It comes with a user-friendly interface (the Z88 Commander), and has a powerful mesh generator. It features a DXF coverter and two plot programs. The FEA solver is included, featuring an in-situ Cholesky solver along with the Jennings storage method. COSMOS and NASTRAN files from Pro/ENGINEER can be imported. Z88 is a project of the University of Bayreuth, Germany.
