2How to scale each continuous design variable
3
4Description::
5Each string in \c scale_types indicates the scaling type for each
6continuous design variable. They only have effect when the associated
7method specifies \c scaling.
8
9The options are:
10
11\li <tt>'value'</tt> - characteristic value by which variables will be
12    divided. If this is chosen, then \ref
13    variables-continuous_design-scales must also be specified; 'value'
14    is assumed if scales are given without \c scale_types
15
16\li <tt>'auto'</tt> - automatic scaling based on bounds.
17
18\li <tt>'log'</tt> - logarithmic scaling (can be used together with
19    \ref variables-continuous_design-scales).
20
21If a single string is specified it will apply to all continuous design
22variables. Otherwise, a scale type must be specified for each
23continuous design variable.

25<b>Usage Tips:</b>
26
27See the scaling information under specific methods, e.g.,
28\c method-*-scaling for details on how to use this keyword.

32Examples::
33Two continuous design variables, one scaled by 4.0, the other by 0.1,
34then further log scaled:
35\verbatim
36  continuous_design = 2
37    initial_point    -1.2      1.0
38    lower_bounds     -2.0      0.001
39    upper_bounds      2.0      2.0
40    descriptors       'x1'     "x2"
41    scale_types =     'value' 'log'
42    scales =          4.0      0.1
43\endverbatim
