\title{Computation and visualization of the empirical attainment function (EAF) for
the analysis of random sets in multi-criterion optimization.}
\description{
The empirical attainment function (EAF) describes the probabilistic
distribution of the outcomes obtained by a stochastic algorithm in the
objective space. This package implements plots of summary
attainment surfaces and differences between the first-order
EAFs. These plots may be used for exploring the performance of
stochastic local search algorithms for biobjective optimization
problems and help in identifying certain algorithmic behaviors in a
graphical way.
