flsgen_structure: Landscape structure solver

Description

Find landscape structures satisfying user targets

Usage

flsgen_structure(
  targets_str,
  targets_file,
  nb_solutions = 1,
  time_limit = 60,
  search_strategy = "DEFAULT"
)

Value

A vector of JSON-formatted landscape structures satisfying user targets.

Arguments

targets_str

JSON-formatted string describing user targets

targets_file

JSON file describing user targets

nb_solutions

Number of solutions to generate

time_limit

Time limit in seconds (if time_limit = 0, no time limit is set)

search_strategy

Choco solver search strategy (for more details refer to Choco solver documentation: https://choco-solver.org/docs/)

Details

The input user targets must be either specified as a JSON-formatted string (targets_str parameter) or as a JSON file (target_file parameter).

Examples

  if (FALSE) {
    json <- "{
      \"nbRows\" : 200,
      \"nbCols\" : 200,
        {
          \"name\" : \"Class A\",
          \"NP\" : [1, 10],
