RapSolved() object.

Details
This table follows Marxan conventions (https://marxansolutions.org/). The columns are:
- Run_Number
The index of each solution in the object.
- Status
The status of the solution. The values in this column correspond to outputs from the Gurobi software package (https://www.gurobi.com/documentation/6.5/refman/optimization_status_codes.html).
- Score
The objective function for the solution.
- Cost
Total cost associated with a solution.
- Planning_Units
Number of planning units selected in a solution.
- Connectivity_Total
The total amount of shared boundary length between all planning units. All solutions in the same object should have equal values for this column.
- Connectivity_In
The amount of shared boundary length among planning units selected in the solution.
- Connectivity_Edge
The amount of exposed boundary length in the solution.
- Connectivity_Out
The number of shared boundary length among planning units not selected in the solution.
- Connectivity_Fraction
The ratio of shared boundary length in the solution (
Connectivity_In) to the total amount of boundary length (Connectivity_Edge). This ratio is an indicator of solution quality. Solutions with a lower ratio will have less planning units and will be more efficient.
