optimizing visited value per distance travelled (sightseeing, tourist problem):

• is it possible to turn tastiness and distance into one weight?

  • weight w = (target tastiness / edge length, edge length)
  • (a, x) + (a, y) = (a, x + y)
  • (a, x) + (b, x) = ((a + b)/2 , 2x)
  • (a, x) + (b, y) = ((x·a + y·b)/(x+y), x+y) = (2x/(x+y) ·a, (x+y)/2) + (2y/(x+y) ·b, (x+y)/2)
  • weights are compared only in the first component

• essential insights:
