Title: Systematic Conservation Prioritization in R
Description: Systematic conservation prioritization using mixed integer
        linear programming (MILP). It provides a flexible interface for
        building and solving conservation planning problems. Once
        built, conservation planning problems can be solved using a
        variety of commercial and open-source exact algorithm solvers.
        By using exact algorithm solvers, solutions can be generated
        that are guaranteed to be optimal (or within a pre-specified
        optimality gap). Furthermore, conservation problems can be
        constructed to optimize the spatial allocation of different
        management actions or zones, meaning that conservation
        practitioners can identify solutions that benefit multiple
        stakeholders. To solve large-scale or complex conservation
        planning problems, users should install the Gurobi optimization
        software (available from <https://www.gurobi.com/>) and the
        'gurobi' R package (see Gurobi Installation Guide vignette for
        details). Users can also install the IBM CPLEX software
        (<https://www.ibm.com/products/ilog-cplex-optimization-studio/cplex-optimizer>)
        and the 'cplexAPI' R package (available at
        <https://github.com/cran/cplexAPI>). Additionally, the 'rcbc' R
        package (available at <https://github.com/dirkschumacher/rcbc>)
        can be used to generate solutions using the CBC optimization
        software (<https://github.com/coin-or/Cbc>). For further
        details, see Hanson et al. (2025) <doi:10.1111/cobi.14376>.
