Optimization time reduced

The time for compiling an optimization problem has been reduced to about 35 % of what is was before. This has been accomplished by compiling the ZIMPL source code with a less extreme precision requirement than the ZIMPL-default. We now use double (16 digits) precision, which is more than enough for the kind of problems solved. For more info on the ZIMPL mathematical program language, see https://zimpl.zib.de.

Bug fixes and other changes

Id	Category	Severity	Summary	Fixed_in_version	Resolution	Comment
0000269	TPG	minor	B3-plots are not regenerated when final felling in period 0	2.13.0	fixed	B3-plots are not regenerated when final felling in period 0
0000244	TPG	minor	No stump harvest when changing control category between generations	2.13.0	fixed	Extraction of harvest residues when final felling was controlled by the settings for the subsequent generation instead of the setting of the current generation. For example, if generation 1 and generation 2 had different settings for whether harvest residues should be extracted, the generation 2 was applied for all generations. This has now been fixed.
0000256	TPG	major	For some stands no tactical program are created if a strategic optimized plan is used as input	2.13.0	fixed	For some treatment units, no tactical program were generated in the following specific case: A strategic optimization was used as starting point when running the Tactical Treatment Program Generator, and some treatments hade been assigned from user-imported treatment proposals. These were not recognized as plausible alternatives when running the tactical TPG. This has been fixed so the tactical TPG enforces a management schedule as close as possible to the one in the strategic solution.
0000267	TPG	minor	"Object reference" fel i TPG	2.13.0	fixed	Already harvested or dead trees were in certain situations considered as candidates for harvest residue extraction, even though they had zero weight. This could lead to an internal referece error.
0000257	TPG	major	Volume function for larch returns negative value for trees with large diameter or height. Solution: Use pine function if dbh >50	2.13.0	fixed	It has come to our attention that the volume function for larch (by Charles Carbonnier) is not applicable for trees with dbh larger than 50 cm, because after that the volume decreases with increasing diameter, due to the function's mathematical form. Volume may even be negativ when diameter approaches 70 cm. Until better functions are available, Brandels volume function for pine (in southern Sweden) is now used for larches with dbh > 50 cm.
0000268	TPG	minor	Generation in Result is always 0	2.13.0	fixed	"B3" is an NFI maturity class that corresponds to R2. This error is very specific for simulations where NFI-data is used input data, and when the young stand B3-plot is located within an older stands.
0000275	Project handling	feature	Remove prompt asking about where to save pricelist, when it's not needed	2.13.0	fixed	Remove prompt asking about where to save pricelist, when it's not needed
0000271	Other	major	Changed pulpwood max diameter is reset to default	2.13.0	fixed	Changed pulpwood max diameter is reset to default
0000277	Other	feature	Plugins can now have custom settings	2.13.0	fixed	Plugins can now have custom settings
0000262	Optimization	feature	Allow copying of parameter of constant or formula type in optimization model	2.13.0	fixed	Allow copying of parameter of constant or formula type in optimization model
0000272	Optimization	tweak	Optimization result and solver meta data mixed in the same output window	2.13.0	fixed	Optimization result and solver meta data mixed in the same output window
0000263	Optimization	trivial	Optimization model syntax-highlight does not work if blank space is missing	2.13.0	fixed	Optimization model syntax-highlight does not work if blank space is missing
0000258	General	minor	Trees in StandWise remain selected for treatment after deselection if "stepping back in time"?	2.13.0	fixed	Trees in StandWise remain selected for treatment after deselection if "stepping back in time"?
0000259	General	minor	Pasting values into timber pricelist puts 0 in last column	2.13.0	fixed	Pasting values into timber pricelist puts 0 in last column
0000255	General	major	(RegWise) Alternative summary and Treatment Data results not display in results table view	2.13.0	fixed	(RegWise) Alternative summary and Treatment Data results not display in results table view
0000264	General	feature	Improve threading performance when calculating pricelists	2.13.0	fixed	Improve threading performance when calculating pricelists
0000260	Data import	major	Young stand simulated when an established stand was expected (due to error in stand register record)	2.13.0	fixed	Young stand simulated when an established stand was expected (due to error in stand register record)
0000250	Data import	major	Simulated young stand completely different from input data	2.13.0	fixed	Simulated young stand completely different from input data
0000276	Data import	minor	Can not simulate initial state for stands where Inventory year is lower than other historic treatments	2.13.0	fixed	Can not simulate initial state for stands where Inventory year is lower than other historic treatments
0000270	Control categories	major	Control table parameters not displayed in Simple View	2.13.0	fixed	Obsolete properties that threw exceptions when called caused the simplified view to not function as intended.
0000254	Control categories	trivial	"RetentionTime in Nature conservation was moved.." message is displayed although project has been updated	2.13.0	fixed	"RetentionTime in Nature conservation was moved.." message is displayed although project has been updated
