Changeset f0464480db in tspsg for src/mainwindow.cpp


Ignore:
Timestamp:
Dec 16, 2009, 11:22:05 PM (15 years ago)
Author:
Oleksii Serdiuk
Branches:
0.1.3.145-beta1-symbian, 0.1.4.170-beta2-bb10, appveyor, imgbot, master, readme
Children:

Parents:

Message:

+ CTSPSolver class now deletes all solution tree on cleanup and delete to avoid memory leaks.
+ List of alternate candidates for branching is now saved in every solution step and displayed on output.
+ New struct TCandidate that represents a candidate for branching.

  • Renamed sStep to SStep and tMatrix to TMatrix.
  • Made a better and more readable About window.
  • English translation is now loaded too. This is needed to support plurals (e.g., 1 candidate, 4 candidates).
