The UE4 uses RecastNavmesh ( GitHub - recastnavigation/recastnavigation: Navigation-mesh Toolset for Games ) you should start lookin from here:

Engine\Source\Runtime\Engine\Private\AI\Navigation\

About your real problem why won’t you implement jump with Nav Link Proxies?

Yes, UE4 use an A* algorithm. If you take a look at the FindPath method of DetourNavMeshQuery class you will find the underlying A* implementation.

Hope this helps.
