| Sensor nodes are often used to guard 3D
domains against intrusion by a foreign object. We have to compute the
size of bottlenecks in any tunnels in the space being monitored.
Coverage against intrusion is guaranteed if bottlenecks are not big
enough to let the object go through. Similar calculations are employed
in designing certain proteins, where access to the active site for the
reacting small molecule is through tunnels. Other related applications
arise in closing holes in cellphone coverage maps, and in computer
aided design (CAD). This talk will present a low level introduction to
the techniques from optimization and algebraic topology employed in
solving such problems efficiently. Undergraduate students are
encouraged to attend.
