This table follows Marxan conventions (https://marxansolutions.org/). The columns are:
The index of each solution in the object.
The status of the solution. The values in this column correspond to outputs from the Gurobi software package (http://www.gurobi.com/documentation/6.5/refman/optimization_status_codes.html).
The objective function for the solution.
Total cost associated with a solution.
Number of planning units selected in a solution.
The total amount of shared boundary length between all planning units. All solutions in the same object should have equal values for this column.
The amount of shared boundary length among planning units selected in the solution.
The amount of exposed boundary length in the solution.
The number of shared boundary length among planning units not selected in the solution.
The ratio of shared boundary length in the
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
