2 You can manage text output in OpenOpt via the following prob parameters:
3 Prob field name           default value
4 iprint                                10
5 iterObjFunTextFormat         '%0.3e'
6 finalObjFunTextFormat        '%0.8g'
7  
8 iprint: do text output each iprint-th iteration
9 You can use iprint = 0 for final output only or iprint < 0 to omit whole output
10 In future warnings are intended to be shown if iprint >= -1.
11 However, some solvers like ALGENCAN have their own text output system, that's hard to suppress, it requires using different approach like, for example, http://permalink.gmane.org/gmane.comp.python.scientific.user/15465
12
13 iterObjFunTextFormat: how iter output objFun values are represented
14 for example, '%0.3e' yields lines like
15  iter    objFunVal
16     0  1.947e+03               
17    10  1.320e+03           
18    ...
19
20 finalObjFunTextFormat: how final output objFun value is represented
21 for example finalObjFunTextFormat='%0.1f' yields
22 ...
23 objFunValue: 7.9

25 See Python language documentation for text format specification.
