S3 method for summarizing moead objects (the output of moead()).
# S3 method for moead
summary(
object,
...,
useArchive = FALSE,
viol.threshold = 1e-06,
ndigits = 3,
ref.point = NULL,
ref.front = NULL
)list object of class moead
(generated by moead())
other parameters to be passed down to specific summary functions (currently unused)
logical flag to use information from object$Archive.
Only used if object$Archive is not NULL.
threshold of tolerated constraint violation, used to
determine feasibility of points in object.
number of decimal places to use for the ideal and nadir estimates
reference point for calculating the dominated hypervolume
(only if package emoa is available). If NULL the estimated nadir
point is used instead.
Np x Nobj matrix containing a sample of the true Pareto-optimal
front, for calculating IGD.
