An FSM model has no conditions along the paths that can affect their traversal; therefore, they are all feasible. However, the paths in EFSMs depend on the input, output, internal variables, operations, and predicates defined over them. Some predicates and condition expressions cannot be ...
(Samet, 1990a;Samet, 1990b). As spatial enumeration schemes, octrees are approximate representations: the quality of the approximation is determined by a fixed resolution. Efficient algorithms, based on a singletree traversal, have been developed toperform Boolean operations on octrees and to ...
during traversal of a first subset of elements of the plurality of elements specifically for collecting data for mapping and/or during normal (e.g., non-mapping specific, etc.) autonomy operations. As an example, when vehicles travel in the world, sensor(s) 210 can log sensor data (e.g...
Given a binary tree, perform the boundary traversal of it. The solution should print the boundary nodes starting from the root of the tree, in an anti-clockwise direction, without any duplicates.
Mathematically, there is a simple way to compute both the area and perimeter of a polygon in a single traversal of its boundary [11]. The area of a polygon can be measured as the sum of areas of all triangles formed by lines that connect the vertices of the polygon to an arbitrary ...
