Consider the single-pair shortest path problem in a weighted directed graph G=(V, E) from a vertex s to t, where s denotes the source vertex and t represents the target/sink vertex. Let dv denote the distance of any vertex v from the source vertex s. Moreover, let w(u, v) represent the weight of the edge (u, v). For each vertex z LaTeX: \ne โ s, consider the set Distancesz, where
Distancesz = { d(u, z) | where d(u, z) = du + w(u, z) for each edge (u, z) in E }
To solve the single-pair shortest path problem using linear programming, we create the following linear program:
maximize dt
subject to
dv - du <= w(u, v) for each edge (u, v) in E
ds= 0
Is it ok that we maximize dt ? Why?
Select all that applies.
a. Yes, because minimizing it would result in an optimal solution where the distances of all vertices would be zero.
b. No. We should formulate it as a minimization linear program.
c. Yes, because an optimal solution requires the distance of the vertex z (i. e., dz) to be the largest value that is less than or equal to the minimum of the values in Distancesz .
d. Yes, because both minimization and maximization would find the shortest path.

"gps interaction and cognitive process" respond to the following: imagine that you have been asked to design a gps product that will have voice recognition and bluetooth capability. discuss and conceptualize a user interaction model. predict two (2) problems that may arise in gps products with voice recognition and bluetooth capability. recommend solutions for each of these issues. attention is one of the six cognition processes. when attention is applied to a design, the goal is to make it easier for the end user to quickly locate where he / she should type information on the computer or mobile device screen. compare and contrast how the google search engine and the microsoft bing search engine employ the attention cognition process. provide your opinion as to which search engine better employs the attention cognition process and explain why.
