add_objective_min_fragmentation_pu: Add objective: minimize planning-unit fragmentation

In multiscape: Multi-Action, Multi-Objective Spatial Planning

Add objective: minimize planning-unit fragmentation

Description

add_objective_min_fragmentation_pu() has been replaced by add_objective_min_fragmentation_planning_units.

Usage

add_objective_min_fragmentation_pu(
  x,
  relation_name = "boundary",
  weight_multiplier = 1,
  alias = NULL
)

Arguments

x	A Problem object.
relation_name	Character string giving the name of the spatial relation to use. The relation must already exist in x$data$spatial_relations.
weight_multiplier	Numeric scalar greater than or equal to zero. Global multiplier applied to the relation weights when the objective is built.
alias	Optional identifier used to register this objective for multi-objective workflows.

Value

An updated Problem object.

Repeated calls

With alias = NULL, one explicit single objective can be defined per problem; a second unaliased definition raises an error. With an alias, objectives accumulate under distinct names; a repeated alias raises an error. Aliased definitions preserve an explicitly configured single objective. To compare alternatives, start from the problem before its objective was added.
