# A-star Variable-length Expand
|
||
|
|
|
||
|
|
Like DFS/BFS/WeightedShortestPath, it should be possible to support the A-star
|
||
|
|
algorithm in the format of variable length expansion.
|
||
|
|
|
||
|
|
Syntactically, the query should look like the following one:
|
||
|
|
```
|
||
|
|
MATCH (start)-[
|
||
|
|
*aStar{{hops}} {{heuristic_expression} {{weight_expression}} {{aggregated_weight_variable}} {{filtering_expression}}
|
||
|
|
]-(end)
|
||
|
|
RETURN {{aggregated_weight_variable}};
|
||
|
|
```
|
||
|
|
|
||
|
|
It would be convenient to add geospatial data support before because A-star
|
||
|
|
works well with geospatial data (heuristic function might exist).
