May 6, 2024 Version 13.00

Improvement of 1D placement algorithm

• Improved partial local solution when there are multiple Stocks panels.
• Improved processing speed when "Merge parts panels of the same size" is unchecked.
• Resolved a small memory leak.

Improvement of 2D placement algorithm

• Due to the algorithm change, the setting item was changed to "Search Level," which is common to the 1D algorithm.
• Even with the "Search Level=0" setting, the placement efficiency is equivalent to that of the rightmost setting in the "Placement Speed and Number of Searches" of the previous version. When "Search Level" is increased, it improves the yield of the type that was difficult to achieve in the previous version.
• Even if the yield itself does not change from the previous version, a diagram that reduces the number of cutting processes within the range that does not reduce the yield is now output.

• Fixed a bug that prevented files from being opened properly depending on the region setting.
