add_default_solver {prioritizr}

Add default solver

Description

Specify that the best solver currently available should be used to solve a conservation planning problem.

Usage

add_default_solver(x, ...)

Arguments

x

problem() object.

...

arguments passed to the solver.

Details

Ranked from best to worst, the available solvers that can be used are: add_gurobi_solver(), add_cplex_solver(), add_cbc_solver(), add_highs_solver(), add_lpsymphony_solver(), and finally add_rsymphony_solver(). For information on the performance of different solvers, please see Schuster et al. (2020).

Value

An updated problem() object with the solver added to it.
