I want to get the optimized geometry of the first triplet state.  MThe input file is as follows.

$CONTRL RUNTYP=Optimize $END
$CONTRL SCFTYP=MCSCF INTTYP=HONDO $END
$CONTRL ICHARG=0 MULT=3 $END
$CONTRL NZVAR=33 $END
$ZMAT DLC=.T. AUTO=.T. $END
$BASIS GBASIS=N31 NGAUSS=6 $END
$BASIS NDFUNC=1 NPFUNC=1 $END
$BASIS DIFFSP=.TRUE. DIFFS=.TRUE. $END
$MCSCF CISTEP=aldet MAXIT=2000 FULLNR=.T. $END
$DET NCORE=19 NACT=10 NELS=10 NSTATE=2 $END
$DET GROUP=C1 ITERMX=2000 $END
$DET WSTATE(1)=0,1 $END
$SYSTEM TIMLIM=10000 MWORDS=100 $END
$P2P P2P=.T. DLB=.T. $END
$STATPT NSTEP=200 $END
$DATA
Molecule specification
C1

$END

However, the output file shows MICIT=1. Why?  AAlso, it appears that it is difficult to converge. How can I fix it?
