- found the relax solution ( at first find three nodes that they had farthest distance from each other ) for tree node
- if sum of distance in relax solution is less than lower bound goto 3 else return
- define V as set of uncoverd vertixes I) for each remainded city do step II II) for all edges in the partial solution III) define θ and compute − ( p2 − p1 )⊤( p1 − c ) / || p2 − p1 || for witch p1p2 is an edge and c is vertix IV) find minimum d defined as distance between c and all p1p2 s in partial solution V) if d is less then or equal to radius of c then c is covered VI) if goto II if any edge reminded else goto VII VII) if goto I if any vertix reminded else goto 4
- compute gamma for all k in V and select a vertex which has greater gamma for next loop
