Chips-n-Salsa, v4.7.0

[4.7.0] - 2022-03-16

Added

• Factory method to LargestCommonSubgraph for creation of instances of the problem
  with strongly regular graphs, specifically such that the instance created consists
  of a pair of isomorphic Generalized Petersen Graphs.

Chips-n-Salsa, v4.6.0

[4.6.0] - 2022-03-14

Added

• Factory method QuadraticAssignmentProblem.createInstance for creating QAP instances
  from specified cost and distance matrices.
• Constructor for LargestCommonSubgraph class for creating instances from lists of
  the edges of the two graphs.

Changed

• Migrated all JUnit tests from JUnit 4.13.2 to JUnit Jupiter 5.8.2.

Chips-n-Salsa, v4.5.0

[4.5.0] - 2022-02-22

Added

• Implementation of the Largest Common Subgraph problem

Changed

• Bumped dependency jpt to 3.1.1
• Bumped dependency rho-mu to 1.2.0

Chips-n-Salsa, v4.4.0

[4.4.0] - 2022-02-13

Added

• Quadratic Assignment Problem

Chips-n-Salsa, v4.3.0

[4.3.0] - 2022-02-11

Added

• Linear Rank Selection
• Linear Rank Stochastic Universal Sampling
• Exponential Rank Selection
• Exponential Rank Stochastic Universal Sampling
• Implementation of the Bin Packing Problem, including instance generators

Changed

• Bumped dependency org.cicirello.core to 1.1.0

Chips-n-Salsa, v4.2.1

[4.2.1] - 2022-01-27

Fixed

• Implemented the optional method, minCost, of the OptimizationProblem and
  IntegerCostOptimizationProblem classes in all of the various TSP implementations
  to return a simple, extremely loose, lower bound of 0, to enable using the
  InverseCostFitnessFunction class that require a finite lower bound. The default
  implementation of that method otherwise returns negative infinity.

Chips-n-Salsa, v4.2.0

[4.2.0] - 2022-01-24

Added

• Class RandomTSPMatrix that enables generating random instances of the Traveling Salesperson
  Problem (TSP) as well as the Asymmetric TSP (ATSP) by generating a random distance matrix. This
  new class includes the option to generate a random distance matrix that enforces the triangle
  inequality. The library had previously introduced a TSP class in a prior release that bases the
  instances on points in 2D space with a user defined metric. This new RandomTSPMatrix class
  compliments that class by additionally providing the ability to specify arbitrary distance matrices
  for a TSP instance.

Changed

• Refactored existing Traveling Salesperson Problem classes (all non-breaking changes)
  to ease the addition of other variations.

CI/CD

• Integrated Snyk code scanning on pushes/PRs.

Chips-n-Salsa, v4.1.0

[4.1.0] - 2022-01-13

Added

• Transformation between Permutation problem and BitVector problem, enabling using operators
  for BitVectors when solving Permutation problems.

CI/CD

• Revised CI/CD workflows to deploy API website changes automatically upon each new release.
