A note on minimum linear arrangement for BC graphs
A linear arrangement is a labeling or a numbering or a linear ordering of the
vertices of a graph. In this paper we solve the minimum linear arrangement
problem for bijective connection graphs (for short BC graphs) which include
hypercubes, M\"{o}bius cubes, crossed cubes, twisted cubes, locally twisted
cube, spined cube, -cubes, etc. as the subfamilies.Comment: 6 page
Embedding onto Wheel-like Networks
One of the important features of an interconnection network is its ability to
efficiently simulate programs or parallel algorithms written for other
architectures. Such a simulation problem can be mathematically formulated as a
graph embedding problem. In this paper we compute the lower bound for dilation
and congestion of embedding onto wheel-like networks. Further, we compute the
exact dilation of embedding wheel-like networks into hypertrees, proving that
the lower bound obtained is sharp. Again, we compute the exact congestion of
embedding windmill graphs into circulant graphs, proving that the lower bound
obtained is sharp. Further, we compute the exact wirelength of embedding wheels
and fans into 1,2-fault hamiltonian graphs. Using this we estimate the exact
wirelength of embedding wheels and fans into circulant graphs, generalized
Petersen graphs, augmented cubes, crossed cubes, M\"{o}bius cubes, twisted
cubes, twisted -cubes, locally twisted cubes, generalized twisted cubes,
odd-dimensional cube connected cycle, hierarchical cubic networks, alternating
group graphs, arrangement graphs, 3-regular planer hamiltonian graphs, star
graphs, generalised matching networks, fully connected cubic networks, tori and
1-fault traceable graphs.Comment: 12 Pages, 5 Figure
