One thing I notice was that I used

a = Array.new
b = Array.new
0.upto( size - 1 ) do |i|
  a[i] = Array.new(size, 0)
  b[i] = Array.new(size, 0)
end

while you used

tos = Array.new
tng = Array.new

0.upto(N) { |row|
  tos[row] = Array.new(N+1)
  tng[row] = Array.new(N+1)
  tos[row] = [0, 0, 0, 0, 0, 0, 0, 0]
  tng[row] = [0, 0, 0, 0, 0, 0, 0, 0] }
  
==========

Is there any difference? It seems easier to use

tos[row] = Array.new(N+1, 0)

rather than

tos[row] = [0, 0, 0, 0, 0, 0, 0, 0] .
