TS optimization

[yimanu]

Hi Teo and everyone

It appears there is still some problems, I am running cp2k compiled
from today's CVS but I keep getting the error
below, saying that the line spearch method is not implemented for CG,
I have used all the line search methods
avialable in cp2k.

*
 *** 18:28:05 ERRORL2 in cg_utils:cg_linmin processor      0
err=-1000  ***
 *** UNIMPLEMENTED, Line Search type not yet implemented in CG for
TS    ***

search.

 ===== Routine Calling Stack =====

           10 cg_linmin
            9 cp_cg_main
            8 geoopt_cg
            7 cp_rot_opt
            6 cp_eval_at_ts
            5 cp_eval_at
            4 cp_cg_main
            3 geoopt_cg
            2 cp_geo_opt
            1 CP2K

Part of the input:

&MOTION
  &GEO_OPT
     TYPE TRANSITION_STATE
     OPTIMIZER CG
     MAX_ITER 500
     &CG
        &LINE_SEARCH
                TYPE 3PNT
        &END LINE_SEARCH
     &END CG
     &TRANSITION_STATE
        &DIMER
                &ROT_OPT
                        OPTIMIZER CG
                &END ROT_OPT
        &END DIMER
    &END TRANSITION_STATE
  &END GEO_OPT
&END MOTION


any comments is appreciated
