We discuss the approximability of this problem and the relation between the unsplittable shortest path routing paradigm and other routing schemes. We show that MinConUSPR is NP-hard to approximate within a factor of O(|V|1-ε), but approximable within min(|A|, |K|) in general. For the special cases where the underlying graph is an undirected cycle or a bidirected ring, we present constant factor approximation algorithms. The connectivity of a communications network can sometimes be enhanced if the nodes are able, at some expense, to form links using an external network. In this talk we survey some of the most recent uses of the decomposition theory in the study of classes of even-hole-free graphs.

Joint activities of this kind can provide valuable and we believe necessary opportunities for employers to keep abreast of current educational developments and for schools to be aware of changes in patterns of employment and of opportunities which are available. The optimization of intensity modulated radiotherapy (IMRT) for charged particle beams is a necessary prerequisite to evaluate the clinical potential of this treatment bookkeeping for startups modality in comparison to IMRT with high energy photons. A theoretical study for IMRT with charged particle beams delivered by rotation therapy is presented. First, the inverse problem for two-dimensional rotation therapy with arbitrary depth dose curves is formulated. Then a numerical strategy is devised to calculate fluence profiles for the simplified case of arbitrary rotationally invariant dose distributions.

We emphasise again that discussion both with the teacher and with other pupils is a necessary part of this process. A few children pass through the various stages of mathematical development in rapid succession and need to advance to more challenging and more abstract work before they leave primary school. For the majority, however, the transition from the use of concrete materials to abstract thinking takes place slowly and gradually; and even those children to whom abstract thinking appears to come easily often need to undertake practical exploration at the beginning of a new topic. 294 As well as drawing graphs which provide factual information, some children should be able to construct graphs which display mathematical relationships such as those of the multiplication tables or of the growth of squares and cubes. Games such as ‘Battleships’ can be used to introduce the idea of co-ordinates to identify spaces and, later, single points; it then becomes possible to record graphically relationships such as ‘pairs of numbers which add up to 10’. Many of these activities provide a basis from which later work in algebra can develop.

We consider two models, one where only the waiting costs of jobs are private information (1-d), and another where both waiting costs and processing times are private (2-d). An optimal mechanism minimizes the total expected expenses to compensate all jobs, while it has to be Bayes-Nash incentive compatible. We derive closed formulae for the optimal mechanism in the 1-d case and show that it is efficient for symmetric jobs.

We welcome the increase in numbers of students training to teach mathematics if their degree courses have contained a substantial mathematical component. On the other hand, we view with some concern the fact that students whose degree subject is completely unrelated to mathematics should be accepted for a PGCE course in mathematics. We agree that ‘these students are likely to swell the numbers of those whose qualifications are inadequate or inappropriate for the work that they are being asked to do’ (5). We do not think that, within the time allotted to most method courses, they are likely to be able to learn to present mathematics effectively in the classroom.

We wish to stress that many of the chapters in our report, and especially those in Part 2, are interrelated. Third sector infrastructure organisations are organisations that ‘work behind the scenes’ to support frontline TSOs that provide services direct to users. They provide their members, or organisations within their geographic area, with a range of services, development and advocacy support.
