Thus we improve the bounds of both problems. More importantly, the techniques we give hold the promise of achieving similar log .-factor improvements in other problems on such graphs.

The importance of bit complexity — as opposed to message complexity — stems also from the fact that in the lower bound discussion, no assumptions are made as to the nature of the algorithm.

Efficient self simulation algorithms for reconfigurable arrays,f the underlying mesh efficient simulations are presented, paying by an extra factor which is polylogarithmic in the size of the simulated mesh. Although the self simulation algorithms are complex and require extensive bookkeeping operations, the required space is asymptotically optimal.

Optimal upward planarity testing of single-source digraphs, .(.) space. The algorithm also constructs an upward planar drawing if the test is successful. The previous best result is an .(..)-time algorithm by Hutton and Lubiw. No efficient parallel algorithms for upward planarity testing were previously known.
