net.simplace.sim.control.generators.LHSSimGenerator

Generate simulations with parameters created using random Latin hypercube sampling

Example

Three dimensional hypercube with 1600 samples:

|  <generator id="LHSSG" class="net.simplace.sim.control.generators.LHSSimGenerator">
|    <cal id="par_a" datatype="DOUBLE" min="0.3" max="1" target="par_a"/>
|    <cal id="par_b" datatype="DOUBLE" min="0.012" max="0.024" target="par_b"/>
|    <cal id="par_c" datatype="DOUBLE" min="0.1" max="1" target="par_c"/>
|    <input id="samples" datatype="INT">1600</input>
|  </generator>
