pSeven 6.16.1 Release

DATADVANCE development team announces the release of the pSeven 6.16.1 update. This release adds the support for exporting approximation models to C# source code and improves handling of unsolvable problem cases in the Design space exploration block. It also contains several bugfixes, in particular, resolving an important issue with malformed result samples in the Design space exploration and Uncertainty quantification blocks.

This release adds the capability to export approximation models trained in pSeven to the C# source code format. This feature is supported by the ApproxBuilder and Approximation model blocks, as well as by predictive modeling tools in Analyze. Model export steps are generally the same as for other formats: see block documentation and section Model Import and Export in the pSeven user manual. Note that exporting models to C# requires an updated license file, which enables this feature.

pSeven 6.16.1 also resolves an important issue with result samples in the Design space exploration and Uncertainty quantification blocks, which was kindly pointed out by our customers. A configuration bug in these blocks could shift the column order in output samples, leading to misinterpretation of results and other adverse effects. Note that while the bug is fixed in 6.16.1, your workflows created in pSeven 6.16 and previous versions may contain blocks saved with invalid configuration. pSeven 6.16.1 provides a way to discover and resolve these issues - see pSeven user manual sections Design space exploration - Known Issues and Uncertainty quantification - Known Issues.

pSeven 6.16.1 is a recommended update which contains all enhancements introduced in pSeven 6.16 and fixes several issues, which you can find described in the release changelog. If you are planning to update from an earlier version of pSeven, it is also recommended to skip pSeven 6.16 and update directly to pSeven 6.16.1.
