Bind the theoretical best record

The theoretical best basis is usually known for a simulated problem. Augment this information into the data object allows for evaluating the performance of optimisation against the theory.

bind_theoretical(dt, matrix, index, raw_data)

Arguments

dt

a data object collected by the projection pursuit guided tour optimisation in the tourr package

matrix

a matrix of the theoretical basis

index

the index function used to calculate the index value

raw_data

a tibble of the original data used to calculate the index value

Value

a tibble object containing both the searched and theoretical best bases

best <- matrix(c(0, 1, 0, 0, 0), nrow = 5)
tail(holes_1d_better %>% bind_theoretical(best, tourr::holes(), raw_data = boa5), 1)
