Meeting scheduler for groups of people in mobilities at different places. It includes the analysis of flights and lodging prices to return the better date and place for everyone to travel together.

Mobility Meeting Scheduler

Usage

SICStus

To run the SICStus program, execute the following command in the root directory of the project:

</path/to/sicstus> -l source/sicstus/main.pl --goal "<run_predicate>."

run_predicate is one of:

1. run('/path/to/input/folder');
2. run('/path/to/input/folder', SearchParameters);
3. run('/path/to/input/folder', SearchParameters, Statistics).

The parameters for the predicates are:

• SearchParameters is a list of parameters for labelling of the clpfd library, which means it can include:
  • One of [leftmost (default), min, max, ff, ffc];
  • One of [step (default), enum, bisect];
  • One of [up (default), down];
  • Running the first command is equivalent of running the second with [min, bisect, down].
• Statistics is one of false, fd or all.
  • Running the second command is equivalent of running the third one with false.

In the input folder the program will expect two files:

• flights.json;
• students.json.

To test it with our input files and default search parameters, run:

</path/to/sicstus> -l source/sicstus/main.pl --goal "run('data/new')."

And, to execute it with the same files, fd statistics and [min, step, up] as the search parameters run:

</path/to/sicstus> -l source/sicstus/main.pl --goal "run('data/new', [min], fd)."

OR-Tools

To run the OR-Tools version of the program you first need to install OR-Tools on your computer

Then just use the following command on the "or-tools" folder:

python main.py

To run the other implementation of a solution to this problem just use the same command but in the "old" sub-folder.

DOcplex

To run the DOcplext version of the program, execute the Jupyter Notebook on source/cplex/model.ipynb.
