add_binary_decisions: Add binary decisions

In prioritizr/ppr: Optimal Project Prioritization

Add binary decisions

Description

Add a binary decision to a project prioritization problem(). This is the conventional decision of either prioritizing funding for a management action or not.

Usage

add_binary_decisions(x)

Arguments

x	ProjectProblem object.

Details

Project prioritization problems involve making decisions about how funding will be allocated to management actions. Only a single decision should be added to a ProjectProblem object. If no decision is added to a problem then this decision type will be used by default. Currently, this is the only supported decision type.

Value

ProjectProblem object with the decisions added to it.

             "name", "success", "name", "cost", "name") %>%
     add_max_richness_objective(budget = 200) %>%
     add_binary_decisions()

# print problem
