The Game of Nim
By Michael J. Reske
Abstract:
  We give a provably winnable strategy in the game of nim.

Successive Sets and Nim-Sequences
By Scott C. Reske
Abstract:
  We look at subtraction games, and more specifically, at successive sets in subtraction games, looking for ways to predict the nim-sequences for them.  In doing so, we determine tat the nim-sequence for any successive set {s1,s2,s3,…,sk} begins with s1 zeros, followed by s1 ones, followed by s1 twos, ad so on until we reach the term s1+sk of the sequence.

Breaking Chairs
By Brian M. Nach
Abstract: 
We will determine a winning strategy for the game COUPLES by showing that it is equivalent to a game in which a winning strategy has been determined in the book Winning Ways.

Population Migration and Equilibrium Populations
By Tomislav Galac
Abstract: 
Beginning with a simple case of migration of population between two states, we proceed to analyze the more general case of n states with free population flow among them.  We find that, assuming constant migration rates, the population in the states will reach an equilibrium point at which the yearly migration will stop affecting the population of any single state.

Reach Out and Touch Someone:  A Mathematical Look at Connectivity
By Shawn Chiappetta
Abstract:
  Given incidence matrices of n-chains or 2-by-n ladders, we find that there is a special eigenvector found by an “easy-to-compute” method.  We also find that the eigenvectors of n-chains and 2-by-n ladders are very similar.
