### Examples

```library(CoopGame)
prenucleolus(c(1, 1, 1, 2, 3, 4, 5))

#Example 5.5.12 from Peleg/Sudhoelter, p. 96
library(CoopGame)
prenucleolus(c(0,0,0,10,0,0,2))
#Output
#[1]  3  3 -4
#In the above example nucleolus and prenucleolus do not coincide!

library(CoopGame)
prenucleolus(c(0, 0, 0, 0, 5, 5, 8, 9, 10, 8, 13, 15, 16, 17, 21))
# [1] 3.5 4.5 5.5 7.5
