 ## Status
 At the moment I'm focusing on implementing an LKH solver (also in Rust). Thus, many features of the parser are still missing, but will be gradually added.
 
-The library can currently parse the following problems from TSPLIB:
-:ballot_box_with_check: TSP - symmetric travelling salesman problem
-:ballot_box_with_check: HCP - Hamiltonian cycle problem
-:black_square_button: ATSP - asymmetric travelling salesman problem
-:black_square_button: SOP - sequential ordering problem
-:black_square_button: CVRP - capacitated vehicle routing problem
-:black_square_button: Tour - a collection of tours

 **NOTES**:
 - The files ```si175.tsp```, ```si535.tsp```, ```si1032.tsp``` from the TSP dataset require a small change: the type entry in the second line ```TYPE: TSP (M.~Hofmeister)``` is wrong according to the format definition. Instead, that line should simply be ```TYPE: TSP```.
