Project a point on the tropical projective torus onto a tropical polytope
Description
This function projects points in the tropical projective torus onto a max- or min-plus tropical polytope based on tropical distance
Usage
project.pi(D_s, D, tadd = max)
Arguments
D_s |
matrix where each row is a point defining a tropical polytope |
D |
point to be projected onto D_s |
tadd |
function; max indicates max-plus addition, min indicates min-plus addition. Defaults to max. |
Value
projection of point D onto the tropical polytope defined by D_s
