v1.2 CPQ Cores

This release again focuses on introducing a number of CPQ related utilities, most notably CPQ core computation. These features were added for use in my Master's Thesis project.

Notable changes:

• CPQ Core computation.
• CPQ Homomorphism testing.
• The Graph class was renamed to UniqueGraph.
• Added SimpleGraph which is more performant than UniqueGraph but also limited to unlabelled undirected graphs without parallel edges.
• Tree implementation for tree graphs.
• Various utility extensions to the existing CPQ and QueryGraphCPQ APIs.
  • Getting the diameter of a CPQ.
  • Checking if a CPQ is a loop.
  • More CPQ construction subroutines.
  • Option to reverse a query graph.
  • Support for parsing text form CPQs.
• GraphPanel not supports undirected graphs.
• GraphPanel factory methods to quickly show CPQs/query graphs/unique graphs.
• Tree decomposition algorithm implementation for graphs of treewidth at most 2.
• Support to copy unique graphs, rename nodes in them and restore deleted edges.
• Maximal matching algorithm implementation
• Cartesian product algorithm implementation
• All subsets algorithm implementation.
• Update to Java 17 and minor code improvements.

v1.1 CPQ Utilties

This release includes various utilities for working with CPQs. Notably, random CPQ generation and CPQ query graph generation. Most of these features were introduced for the CPQ Keys project: https://cpqkeys.roanh.dev/

v1.0 Initial Release

The initial public release of the gMark rewrite. This version only has support for CPQ based queries but does provide a graphical interface. There is no support for graph generation or RPQ based queries in this version.
