MOGA optimizer for rings

[Zeus]

Hi all,

I'm sad to say I'm stack at step 1 of the GuideToUse. The first time I ran plotTwiss it produced some errors since HOST_ARCH and EPICS_HOST_ARCH were not defined, once I assigned those variables as:

export HOST_ARCH=linux-x86_64
export EPICS_HOST_ARCH=linux-x86_64

plotTwiss gives the following error:

averageOverElements: couldn't execute "averageOverElements": no such file or directory

any idea what I'm missing?

Thanks

plotTwiss and averageOverElements, along with many other scripts, are not included in any binary release. Instead they are in:
https://ops.aps.anl.gov/downloads/oag.1.25.tar.gz
After you unpack this, you will find the programs in oag/apps/src/tcltkapp/oagapp

Hello everybody,

I'm using MOGA for optimization DA in my lattice, but there is a problem. I want to do tracking for 1024 turns, so in runJob1, I increased the number of turns to 1024 but the DA is different in two different situation;
1. plot DA by optim1-******.aper
2. track optim1-******.new in elegant and plot the results of tracking.
In second situation when I put
&run_control
n_passes = 400
&end
the results are similar to each other, so I know the problem is the number of turns in first and second method, I change the number of turns in runJob1 but it doesn't work. Can you help me in this problem?

regards,
Sara

Thanks soliday,

Still fighting with the aps example, when trying to run:

geneticOptimizer -input optim1.sdds -reduce 1

I get the following error:

Error: optim1.all file found but -contin 1 not given

Any idea what is wrong?

Hello Zeus,
As I know you should use this command;
geneticOptimizer -input optim1.sdds -reduce 1 -contin 1

Hello every body,
Do you have any idea about the algorithm which is used for sorting results in this MOGA example? Is it NSGA-II?

regards,
Sara

Sara,

We use an independent implementation based on the ideas in NGSA-II. The non-dominated sorting algorithm is the one described by Srinivas and Deb.

Hello,

I am trying to run the moga scripts on a computer. The computer already has elegant-2019.1.1-1.rhel.7.openmpi.x86_64.rpm as well as SDDSToolKit-4.1-1.rhel.7.x86_64.rpm. I understand that I have to install the OAGTclTk as well. I tried installing the OAGTclTk-1.25-2.rhel.7.x86_64.rpm but I get a file conflict error:

file /usr/bin/caRepeater from install of OAGTclTk-1.25-2.x86_64 conflicts with file from package SDDSEpicsToolKit-3.6-1.x86_64

Is it ok to force the install?

Thanks,

Evan

Hello


I have a problem with oagtclsh. I am working through the installation of elegant on a remote cluster in order to do MOGA calculations.


I believe I have successfully compiled:
epics/base
epics/extensions/SDDS

epics/oag

/home/bertwid/epics/oag/apps/src/elegant

I have worked through the Guidetouse under mogaRing up to running plotTwiss

I get the following result:


/epics/oag/apps/bin/linux-x86_64/plotTwiss: line 3: exec: oagtclsh: not found

I've done a recursive grep for oagtclsh on ~/epics. The file does not exist or has not been created as part of some step?

I thought it might be provided/created by oag.1.25.tar.gz. I tried unpacking oag.1.25.tar.gz. It adds directories for applications at the same level as elegant. I tried to run make from /home/bertwid/epics/oag/apps/src/tcltkinterp and get the following error (I ran make in this directory hoping that this application would provide oagtclsh. Perhaps it doesn't?
