Because there are many `SoCG topics' which are not computational geometry, but got in because of an overlap of interests in the persons of some traditional members of the SoCG community. Some combinatorial geometry got in, and a subset of discrete geometry essentially defined by being a side interest of a<BR/>core SoCG member, e.g. recently transversal questions. This leads to the illusion that SoCG is really the conference of Discrete and Computational Geometry, but it is not, there is a big Discrete Geometry community out there which is not related to the SoCG community. E.g. the community of the hungarian `Intuitive Geometry' conferences, as long as they existed, is, with the exception of the combinatorial geometry part, disjoint to the SoCG community. The polyhedra people are disjoint. And there are a number of other groups and topics, whose inclusion or exclusion in SoCG depends on whether there is a core SoCG member that also works on that topic. <BR/><BR/>Thus the SoCG is automatically a meeting defined not only by topic, but to a certain degree by group membership. If the conference would restrict itself to really core computational geometry, this problem would not exist, but exactly the attempt to `broaden the coverage' leads to a broadening defined by group membership. And that leads to disappointed expectation in those who are outside the core, but think that they are not more distant to the core than others who did get accepted.<BR/><BR/>So I think that a more restrictive view of the topic, aiming to accept all competent papers on computational geometry, but rejecting the papers outside the topic, would make the decision process less controversial.<BR/><BR/> Peter BrassAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2166612071923681799.post-40436506320119811042007-06-22T10:45:00.000-04:002007-06-22T10:45:00.000-04:00About so-called "core" and "non-core" Computationa...About so-called "core" and "non-core" Computational Geometry.<BR/><BR/>Of course, there is no clear-cut separation here, but one might define the "core" of Computational Geometry, as the subjects that form traditionally the main part of SoCG, or subjects that many members of the SoCG program committe are familiar with, and would feel comfortable to review.<BR/><BR/>For example, a paper about Voronoi diagrams or Delaunay triangulations it most probably core CG; a paper about planar graphs with graph-theoretic techniques, with has <I>some</I> connection to geometry, is "non-core" CG. Anything radically new is by definition "non-core" CG.<BR/><BR/>This is not meant to exclude "non-core" CG from SoCG. But even if one does not like it, this distinction exists, and it will naturally tend to reflect itself in the decisions of the committee, and unless one makes a conscious effort to fight it, it will tend to perpetuate itself, and make it hard for new trends or new ideas to become established.<BR/>--<BR/>Günter RoteAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2166612071923681799.post-47604829146943209382007-06-19T13:28:00.000-04:002007-06-19T13:28:00.000-04:00Another remark: like Siggraph, SoCG has also no pr...<I>Another remark: like Siggraph, SoCG has also no predefined number of accepted papers.</I><BR/><BR/>Again this is not so.

Even though the final number is rather stable through years. <BR/><BR/>I already see SoCG as the conference (maybe not the only one) I would like to attend regularly. Still, we don't have a budget that is large enough to send all members of the group every year...

Many topics and accomplishments in <BR/>computational geometry should be things that high school and <BR/>undergraduate mathematics teachers and undergraduate CS teachers <BR/>should know about. (The ultimate goal being public awareness in <BR/>general.) Especially when there is work that results in applications <BR/>that affect people in everyday life this information should be made <BR/>available to teachers.

(p.57)<BR/><BR/>SoCG should ideally be the conference where everybody who is attached to computational geometry and has no conflicting obligations would regularly want to go, to hear the latest results and keep up-to-date, to present their results, and to meet and talk to people.<BR/><BR/>This time, not even all authors of accepted papers were present (which might partly due to the remote location for many people and to the competition of the adjacent Japanese conference).<BR/><BR/>I think we could accept more papers without compromising the quality of the conference, as viewed by how interesting it is for the participants.<BR/>My experience on program committees was that there was in the end a tough decision about some remaining papers that could have gone either way, and we could have accepted all of these had it not been for limited space in the proceedings and limited time at the conference. In this final stage, it is more likely for papers that are not "core" computational geometry, that are at the fringe, to get rejected.<BR/><BR/>This is, sadly, in conflict with the explicit goal of encouraging "applications", "software", "experimental" papers, and papers from related fields.<BR/><BR/>We should try to explore different formats which allow more people to participate, and at the same time keep the conference competitive.<BR/>I would personally be in favor of reviving the poster session, for example.<BR/><BR/>Releasing pressure in this direction, in one way or another, might make the discussion about "consistency of standards" or "accountability for one's judgements" obsolete.<BR/>(If a paper is rejected for no better reason than that there were other papers that were considered better, what would be "proper feedback" in this case?)<BR/>-- <BR/>Günter RoteAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2166612071923681799.post-14482100136817896882007-06-14T14:43:00.000-04:002007-06-14T14:43:00.000-04:00Accept more papers (facilitated by making the talk...Accept more papers (facilitated by making the talks shorter and having more parallel sessions), and thus, more people.Hermannoreply@blogger.comtag:blogger.com,1999:blog-2166612071923681799.post-5472437406330094382007-06-14T13:50:00.000-04:002007-06-14T13:50:00.000-04:00I believe Computational Geometry should be taken i...I believe Computational Geometry should be taken in a rather eclectic<BR/>sense: anything involving algorithms and calculations on geometric<BR/>objects, with a mathematical inclination, should fall in its realm. a<BR/>recent initiative in this spirit is certainly the Symposium on<BR/>Geometry Processing, as one finds there attendees from classical CG,<BR/>CAGD and Computer Graphics/Geometry Processing. to broaden the scope<BR/>of SoCG, I believe two things would help a lot:<BR/><BR/>1. a better and more open review process --see the thread on Best<BR/>Practices, meant to serve an expanded sense for 'Computational<BR/>Geometry'.<BR/><BR/>2. an acknowledgment of the fact that privileged ways to disseminate<BR/>geometric ideas and concepts in other communities are quality software<BR/>and applied papers. unfortunately, papers dealing with complete and<BR/>robust implementations often look tedious to people essentially<BR/>interested in generic situations and complexity issues, so that<BR/>getting such papers accepted gets more and more difficult. cf also the<BR/>CG Task force.Frederichttp://www.blogger.com/profile/18179382692515751602noreply@blogger.com
