I have to converte an algorithm into a script in python but i don't know how

Question

The algorithm describes a method in combinatorial optimization called local search using a table of numbers :

Algorithm 1: Local search for 1 / ri / Tmax
Entries: integers n; arrays of n integers p, r and d; arrays of n integers t [.], c [.], T [.] and
the integer Tmax
Outputs: arrays of n integers t [.], c [.], T [.] and the integer Tmax
1 repeat
2 improvement <- false;
3 Let k is in {2 ,..., n} such that T [o [k]] = Tmax.
4 Find l in {1 ,..., k - 1} such as replacing the task o [k] to position l and shifting the tasks o [l], ..., o [k - 1] by one cell to the right reduces Tmax;
5 if l exists then
6 improvement <- true ;
7 Replace task o [l] into position k and shift tasks o[l], ..., o [k - 1] of a cell to the right;
8 Update the tables t [.], c [.], T [.] and the integer Tmax;
9 end if
10 until improvement = false;

Answer 1

Please what is ri?
