 whereas they would not be combined in an independent-thread implementation.  Table 00.0  Speedups for multiple-walk cooperative-thread implementations of GRASP with path-relinking on instances abz0, mt00, orb0, and la00, with target values 000, 000, 000, and 0000, respectively. Average speedups were computed over 00 runs. | Number of processors  ---|---   |  0 | 0 | 0 | 00  Problem | speedup | efficiency | speedup | efficiency | speedup | efficiency | speedup | efficiency
