The objective is to determine an efficient traversal that minimizes the maximum amount of memory of each type needed to traverse the whole tree. In this paper, we establish the complexity of this two-memory scheduling problem, provide inap-proximability results, and show how to determine the ...

Finally, the relationship between algorithm and performance, to measure the quality of an algorithm, mainly evaluates time and space by the amount of data, which will directly affect the program performance in the end. Generally, the space utilization rate is small, and the time required is rela...
This result is rather surprising for two reasons: First, the problem is tractable on trees [22] and often problems that become easy on trees turn out to be fixed-parameter tractable when parameterized by treewidth.1 Second, this makes Secure Set one of the very few "subset problems" that ...
The approach used in the design of the FPT algorithm also leads to anO(n)-time testing algorithm forst-graphs of treewidth at most two (also known as two-terminal series-parallel graphs) in the fixed embedding setting (Theorem7). We recall that in the variable embedding setting anst-graphs...
Thirty adults read a binary-tree-structured hypertext to answer three 2-part questions on the topic of cosmology. Results confirmed the following hypotheses: (a) successful readers chose only important nodes to read, (b) questions that required more node traversal were more difficult to answer, ...
