keywords:
PRINT-LEVEL (integer)
START-PRINTING-AT-ITERATION (integer)
STOP-PRINTING-AT-ITERATION (integer)
ITERATIONS-BETWEEN-PRINTING (integer)
These words control the amount of output that is required at each
iteration of the optimization procedure.
The PRINT-LEVEL keyword indicates the level of printing
required. If no printing is required at all, the integer value
following the keyword should be set non-positive. A single line
summary of a specific iteration results if the integer is set to 1;
this summary is expanded slightly when the integer is set to 2. Details
of the current estimate of the optimum value are printed if the integer is
larger than 2 and an increasing level of output is available by
selecting larger integer values. A full debugging print occurs when
the integer is set larger than 100.
The printing starts when the iteration specified on the START-PRINTING-AT-ITERATION iteration is reached and stops after the STOP-PRINTING-AT-ITERATION iteration is passed. Printing occurs at regular intervals. The exact interval may be specified using the ITERATIONS-BETWEEN-PRINTING option. The default settings are
