HuGS

Human-Guided Search (HuGS) is a framework for helping the computer solve computational problems by human interaction.

Authors

HuGS was developed by Neal Lesh, Gunnar W. Klau, Michael Mitzenmacher, and Joe Marks.

Installation/Compilation

There should be a Makefile, but there isn't. Whoever reads this, please add one. Otherwise compile the code using

javac hugs/*java
javac hugs/apps/crossing/*java
javac hugs/apps/delivery/*java
javac hugs/apps/jobshop/*java
javac hugs/apps/protein/*java
javac hugs/apps/stpc/*java

Usage

To run the programs, try

java hugs.apps.crossing.Crossing -size 10 5
java hugs.apps.delivery.Delivery
java hugs.apps.protein.Protein -size 50
java hugs.apps.jobshop.Jobshop -loadProblem apps/jobshop/problems/la16.jsp

The last assumes you are in the hugs directory. You can, of course, run the programs without any arguments, but the above give samples of how to specify the problem.

Here are a few of the less obvious features of the system:

  • Double-click on the background to unselect all elements

  • The red, yellow, and green squares near the score are shortcuts for setting mobilities. Click on them once to set the mobilities of the selected elements.

  • Double-click on the mobility icons to set the mobility of all elements.

  • The Selections menu allows you to mark (and unmark) elements. Some of the applications allow you to specify secondary objective functions on marked elements, by controlling the inputs to the search algorithm (press the "Inputs" button to get the controls) For example, in Crossing you can tell the search algorithm to move marked elements to the left or right.
