New Optimization Wizard
A new optimization wizard has been added to PlanWise. You can find it in the Optimization Model-tab by either selecting "New model" or directly from "Model Wizard". Together with the optimization wizard we have also added an area
The optimization wizard enables users to quickly construct an optimization model by choosing decision variable, optimization target (objective function), and constraints, directly from a dialog.
The model explorer makes it easy to overview your library of models.
Example of selection the decision variable in the wizard.
Example of adding constraints in the wizard.
New Features

Changes
- Carbon and nitrogen from the spinup period are now grouped into the initial stock. Net input is carbon and nitrogen from decomposition of plant material accumulated since the simulation start.
- Support for version of Gurobi older than 9+ has been removed. This follows Gurobi's list of supported versions .
- Support for version 10.0 of Gurobi has been added.
- Rudimentary support for CPLEX 22.10 has been added. There is limited support for CPLEX's return status and other versions of CPLEX.
- The open source solver LpSolve have been replaced by COIN-OR CLP/CBC solver.
Bug Fixes
- Carbon content in above-ground biomass is now calculated from the table in Carbon sequestration
- Fixed an issue where users could not select folders in file dialogs.
- Fixed an issue when splitting a NC-area where the vertices of areas would overlap.
