Imagine two nodes A and B connected by an edge with weight 2. If A is the source node, and every other edge touching it has a larger weight, then the direct path from A to B must be the shortest ...

Using this estimate, the SafePath algorithms can calculate the total risk of a path from one place to another, as well as take into account particularly risky blocks. Ask for directions, and the ...

a, Structure of the organism before finding the shortest path. Blue lines indicate the shortest paths between two agar blocks containing nutrients: α1 (41 ± 1 mm); α2 (33 ± 1 mm); β1 (44 ± 1 ...
