  We present an application, EasyScan_HEP, for connecting programs to scan the
parameter space of High Energy Physics (HEP) models using various sampling
algorithms. We develop EasyScan_HEP according to the principle of flexibility
and usability. EasyScan_HEP allows us to connect different programs that
calculate physical observables, and apply constraints by one human-readable
configuration file. All programs executed through command lines can be
connected to EasyScan_HEP by setting input and output parameters of the
programs. The current version offers the sampling algorithms of Random, Grid,
Markov chain Monte Carlo and MultiNest. We also implement features such as
resume function, parallelization, post-processing, and quick analysis.
