    Description / Table of Contents: Zusammenfassung Wir analysieren die Komplexität von eingeschränkten Linear Arrangement Problemen, bei denen nur solche Permutationen der Knoten erlaubt sind, die durch die Ordnung eines die Knoten des Graphen strukturierenden, binären Baumes — des sogenannten P-tress — entstehen. Derartige Versionen von Linear Arrangement Problemen tauchen an mehreren Stellen in heutigen Schaltkreis Layout Systemen auf. Der P-tree resultiert dabei aus einem rekursiven Zerteiluungsprozeß des Graphen. Wir zeigen, daß das MINCUT LINEAR ARRANGEMENT und das OPTIMAL LINEAR ARRANGEMENT Problem in polynomieller Zeit lösbar sind, wenn der P-tree balanciert ist. Alle anderen betrachteten Versionen von Linear Arrangement Problemen sind NP-vollständig.
    Notes: Abstract We analyze the complexity of the restrictions of linear arrangement problems that are obtained if the legal permutations of the nodes are restricted to those that can be obtained by orderings of a binary tree structuring the nodes of the graph, the so-called p-tree. These versions of the linear arrangement problems occur in several places in current circuit layout systems. There the p-tree is the result of a recursive partitioning process of the graph. We show that the MINCUT LINEAR ARRANGEMENT problem and the OPTIMAL LINEAR ARRANGEMENT problem can be solved in polynomial time, if the p-tree is balanced. All other versions of the linear arrangement problems we analyzed are NP-complete.

    Description: The development of the capability for measurement under global irradiance spectral distribution is reported. The airmass 1.5 global measurement procedure is given. Also given is the procedure and justification for using the large area pulsed solar simulator (LAPSS). The status of the international round robin of reference cell measurements managed by the Commission of European Communities (CEC) is described.
