Bsc

This is the code repository for the Project in Constrained Bayesian Optimization by Alexander Walbækken at the Technichal University of Denmark

Structure

There are several files for running experiments and testing the algoritms. The \Experiments forlder is where local results are stored in numpy format, and also where cached calculations for cizualizations are stored. The \Utils folder contains functions for plotting and storing/loading experiments.

The main ADMMBO algorithm is accesible as an import from \ADMMBO_scaffold.

The Test-problems are contained in \opt_problems, with the problems defined as a dictionary of:

"Bound Type" : <string> (not used exepct in early phase)
"Bounds" : <Tuple of length d*2 with lower, upper bounds for all variables>
"Cost Function (x)":  <amda funcions to evaluate objective>
"Constraint Functions (z)": <List containing lamda funcions to evaluate contraints>
"Best Value": <float> (optional for graphs)

For PESC

When running PESC there are several steps to the setup. After the database is setup, make an anaconda enviroment with the name "pesc" using the file envPESC.yml. The automatic scripts for running PESC as a subproscess should then run.

When making a new problem, a manual addition to the problem files will be needed, then input "yes" when evrything is correctly inserted as per the file outline.

Database

Assuming you are running windows, following this outline could help in the installation.

Add mongoDB ver 2.6.12 from archive in website (https://www.mongodb.com/download-center/community/releases/archive) I installed it on Parent of Bsc directory for simplicity. Also see: https://stackoverflow.com/questions/2404742/how-to-install-mongodb-on-windows

The commands for installation must be run in <MONGODB_PATH>\bin, after being added to path and with administrator priviliges.

If an error occours, I would suffest starting over with (for my installation) D:\mongodb\bin>mongod --remove

Make the folder: \comparisson_algs\PESC_folders\dbfolder Then run: mongod --dbpath=<PATH TO REP>\Bsc\comparisson_algs\PESC_folders\dbfolder --logpath=<PATH TO REP>\Bsc\comparisson_algs\PESC_folders\logfolder\log.txt --install followed by : net start MongoDB

Other changes

PESC env works with c code commeted out in the kernel_utils file of the PESC Spearmint files

• Changed kernel_utils.py so it used the slower python version insted of weave
• Changed print function in tasks/input_space.py line 272 function
  • All 4 in the input_params functiontion into normal print statements

Simnibs

With simnibs as a sub-folder in the project (here named \simhack) This roughly follows the download instruction from https://github.com/simnibs/simnibs,

Eviroment

For the full enviroment have Anaconda in your path and run create an eviroemtn from the envFull.yml file.

• Run the python setup.py develop in administrator terminal for windows from the \simhack directory.
• Intall pyvista pip install
