ProfitContributors: Computes profit contributions for all points in a setup...

In wflo: Data Set and Helper Functions for Wind Farm Layout Optimization Problems

Computes profit contributions for all points in a setup solution.

Description

This function takes an optimizer result (or simple vector object) and computes the profit contribution for each point.

Usage

ProfitContributors(Result)

Arguments

Result

must be an optimization result as returned by an optimizer such as optim or a vector. Usually, this will be a list at least containing '$par'.

Details

Neglecting a possibly invalid setup (caused by at least one point), computes the profit contributions. If the setup provided is valid, the sum of contributions is identical to the (absulute value of the) returned value of Profit.

Value

ProfitContributors returns a matrix of two columns and n rows, whith n being the number of turbines. The first column is a sequence of 1:n, representing the turbine IDs, while the second column contains the actual profit contributions.

See ValidSetup to see how a setup is categorized as valid or not. Use PlotResult to visualize the optimization result.

Examples

#Prints a result and uses the profit contributions as labels.
NumTurbines <- 4
set.seed(1235)
Result <- optim(par = runif(NumTurbines * 2), fn = Profit,
  method = "L-BFGS-B", lower = rep(0, NumTurbines * 2),
  upper = rep(1, NumTurbines * 2))
MyLabels <- ProfitContributors(Result)
MyLabels
#PlotResult(Result, DoLabels = TRUE, Labels = MyLabels[, 2])

# Given a valid setup, this should be TRUE.
#identical(abs(Profit(Result$par)), sum(MyLabels[, 2]))
