Dear OPAL Users,

I would like to use the inbuilt multi-objective optimisation of OPAL but I
have encountered a couple of issues and kindly ask for your help.

- Although I define OPTION, REPARTFREQ = 14; to use 14 cores of my PC it
doesn't allow me to use more than 10 which is the default according to the
manual.

- .tmpl and .in files are working if only I use INITIALPOPULATION=1 but
optimisation doesn't end once it is >1. .tmpl commands are given below.

OPTION, ECHO=FALSE, INFO=TRUE, REPARTFREQ = 14;

TITLE, STRING="OPAL MOO Test for VHF Gun, 2023-10-19";

REAL loc = 1.0;

dv0: DVAR, VARIABLE="KS_I", LOWERBOUND=0.01, UPPERBOUND=0.1;

demitx:   OBJECTIVE, EXPR="fabs(statVariableAt('emit_x', ${loc}))";

OPTIMIZE, INPUT="tmpl/MOO_deneme.tmpl", OBJECTIVES = {demitx},
          DVARS = {dv0}, INITIALPOPULATION=2, MAXGENERATIONS=1,
          NUM_IND_GEN=1, MUTATION_PROBABILITY=0.99,
          NUM_MASTERS=1, NUM_COWORKERS=8, SIMTMPDIR="simtmpdir",
          TEMPLATEDIR="tmpl", FIELDMAPDIR="fieldmaps", OUTPUT="optVHF",
          OUTDIR="results";
