The interval is defined between square bracket.\f2\par \f0 The interval constains two bounds (lower and upper), this bounds are given as double values. To seperate both bounds from each other you can either use two points '..', a semicolon ';' or a white-space ' '.\par Intervals can be specified for example with \f1\fs20 [-inf. .. 0] or [0 .. inf.]\f0\fs22 , which represents a left/right open interval\f1\fs20 .\par \f0\fs22 To define a monotonicity constraint 'f increasing over x' write \f1\fs20\lang3079 df/dx in [0 .. inf.].\par \f0\fs22 To define a concavity constraint write \f1\fs20 d\'b2f/dx\'b2 in [0 .. inf.] or [-inf. .. 0].\par \f0\fs22 To define constraints only on a specific input range e.g. f must be postive for all \f1\fs20 x in [0 .. 1] \f0\fs22 write: \f1\fs20 f in [0 .. 100], x in [0 .. 1\f0 ]\fs22 , the ranges are seperated by commas.\fs20\par \fs22\lang7 To specify different weights on the constraints write: \f1\fs20 f in [0 .. 100], x in [0 .. 1] weight: 2.0\par \f0\fs22 To define partial derivatives you can either use the symbol d or \f3\u8706?\f2\lang7 .\par }
