Much of the system’s power savings depended on its ability to electronically switch off components, such as servos, that draw high levels of quiescent currents.

-          <div class="twocol justify"><p>Back in 2018, we used <a href="https://neo4j.com/" class="external" target="_blank" rel="noopener noreferrer">Neo4J</a> graph database to track the
-movement of marine vessels. We were interested in the shortest path a ship
-could take through a network of about 13,000 route points. Graph theoretic
-algorithms provide optimal solutions to such problems, and the set of route
-points lends itself well to graph-based modelling.</p>
-
-<p>A graph is a finite set of vertices, and a subset of vertex pairs (edges).
-Edges can have weights. In the case of vessel tracking, the route points form
-the vertices of a graph; the routes between them the edges; and the distances
-between them the weights. For various reasons, people are interested in
-minimizing (or maximizing) the weight of a path through a set of vertices, such
-as the shortest path between two ports to predict a vessel’s arrival time.</p>
-
-<p>Given a graph, an algorithm like Dijkstra’s search could compute the shortest
-path between two vertices. In fact, this was the algorithm Neo4J shipped with
-at the time. One drawback of Dijkstra’s algorithm is that it computes all the
-shortest paths from the source to all other vertices before terminating at the
-destination vertex. The time complexity of this exhaustive search prevented our
-database from scaling beyond 4,000 route points.</p>
-
-<p>The following enhancement to Dijkstra’s search, also known as the A* search,
-employs a heuristic to steer the search in the direction of the destination
-more quickly. In the case of our network of vessels, which are on the earth’s
-surface, spherical distance is a good candidate for a heuristic:</p>
