Logically Collective on TaoLineSearch
| ls | - the TaoLineSearch context | |
| prefix | - the prefix string to prepend to all TAO option requests |
For example, to distinguish between the runtime options for two different line searches, one could call
TaoLineSearchSetOptionsPrefix(ls1,"sys1_")
TaoLineSearchSetOptionsPrefix(ls2,"sys2_")
This would enable use of different options for each system, such as
-sys1_tao_ls_type mt
-sys2_tao_ls_type armijo
