      The Steiner Tree Problem is a fundamental network design problem, where the goal is to connect a subset of terminals of a given network at minimum cost. A major open question regarding this problem, is proving that the ...
    • A Primer on Cryptographic Multilinear Maps and Code Obfuscation 

      Mayo, Kenwrick (University of Waterloo, 2015-09-23)
      The construction of cryptographic multilinear maps and a general-purpose code obfuscator were two long-standing open problems in cryptography. It has been clear for a number of years that constructions of these two ...
    • Prioritizing Features Through Categorization: An Approach to Resolving Feature Interactions 

      Zimmer, Patsy Ann (University of Waterloo, 2007-09-27)
      Feature interactions occur when one feature interferes with the intended operation of another feature. To detect such interactions, each new feature must be tested against existing features. The detected interactions must ...
