Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use GAT-PCM to repair assignments without relaxing constraints in DLNS | DLNS · Random DCOPs and scale-free networks | normalized anytime cost | Helped |
| Use GAT-PCM to repair assignments without relaxing constraints in DLNS | DLNS · Small grid networks | normalized anytime cost | Hurt |
| Use GAT-PCM to repair assignments without relaxing constraints in DLNS | DLNS · Grid networks with grid size higher than 14 | normalized anytime cost | Helped |
| Use GAT-PCM predicted costs for domain ordering | PT-ISBB · Random DCOPs and scale-free networks | simulated runtime | Helped |
| Use GAT-PCM to guide DLNS repair instead of existing heuristics | DLNS · Random DCOPs with |I|=1000, p1=0.005, d=3 | solution quality | Helped |
