## Keyword descriptions

BOUNDARIES: real[2]

  Usage: BOUNDARIES LOWER UPPER

  Defines the boundaries to which the optimization is restricted. First value is the lower bound, second value is the upper bound. [Edit on GitHub]

MAX_VAR_FRACTION: real

  Usage: MAX_VAR_FRACTION REAL

  Defines the maximum fractionr by which the exponent is allowed to vary. e.g. 0.5 allows the exp to vary by 0.5*exp in both directions. [Edit on GitHub]

USE_EXP: integer[2]

  Usage: USE_EXP SET IEXP

  Defines the exponent to be constraint. The two integers indicate the set number and i’th exponent. The value -1 can be used to mark all sets/exponents in a set. [Edit on GitHub]
