[EM] calculating the N matrix in Schulze STV

2013-06-29 Thread Alexander Kjäll
Hi I'm trying to implement the Schulze STV method and are currently working through the paper schulze2.pdf. On page 38 there is an example (section 6.3) where this result was arrived at: N[{a,b,c},d] = 169; and Ñ[{a,b,c}, {a,b,d}] = 169; And i can't seem to figure out how to arrive at the

Hallo, N[{a,b,c},d] = 169 or Ñ[{a,b,c}, {a,b,d}] = 169 means that W=169 is the largest value such that the electorate can be divided into 4 disjoint parts T1,T2,T3,T4 such that (1) Every voter in T1 prefers candidate a to candidate d; and T1 consists of at least W voters. (2) Every voter in T2

Vidar Wahlberg, One very simple rule that transcends the dichotomy between a party-list and a candidate-based PR election rule is 3-seat LR Hare. Each party has one candidate and each voter one vote. Typically the top 3 vote-getters would get one seat each, but if the top vote-getter beats the
