Mathematical Programming, Series B Policies and Procedures December 2004 Steve Wright, EIC Each number of Mathematical Programming, Series B (MPB) takes the form of a "special issue" associated with a particular topic or event, such as a workshop or conference. Most such issues have guest editors, appointed by the editor in chief (EIC), who may or may not be associate editors of MPB. Topics for special issues can be proposed by any member of the optimization community. Associate editors (AEs) of MPB have a special responsibility to propose suitable topics and to identify individuals who would be able to guest-edit issues on those topics. A summary of procedures and policies for MPB follows. 1a) Guest editors will draft a "call for papers" for their special issue, in consultation with the EIC and possibly AEs. The call defines the scope of the issue, gives a deadline for submissions, and gives a target date for completion of the first round of reviews. 1b) In most cases, this call will be publicized through optimization-related mailing lists, MPS publications, and personal communication with prospective authors, and will be posted on the Web. When the issue is associated with a workshop or conference, submissions may be restricted to participants in the event and their coauthors. 2) Guest editors will handle submissions for the special issue. They will accept submissions and revisions, assign referees, and correspond with authors and referees. If they determine that a paper should be rejected, their decision is final and should be communicated to the author(s) directly. If they determined that a paper is acceptable, they send the paper and associated correspondence to the EIC, along with their recommendation to accept. 3) Each submitted paper will generally be refereed by at least two people. 4) Where possible, correspondence between the guest editors and authors and referees should be by email. The EIC will arrange for editorial assistance in these matters should the guest editors require it. 5) Guest editors should coordinate the handling of submissions so as to avoid overloading any editor or referee. The form of coordination is flexible, but should include the maintenance of a simple database with an entry for each submission indicating date of receipt, referees, dates of major revisions, dates of acceptance, and current status of the submission. The EIC will arrange for editorial assistance to maintain this database, should the guest editors require it. 6) Editorial standards should be the same as those used for Mathematical Programming, Series A (MPA). Maintaining the quality of the journal is of the highest importance. 7) Upon receiving a recommendation to accept from the guest editors, the EIC will make the final determination on acceptability. This decision will normally be in accord with the recommendation of the guest editors and will normally be communicated quickly by the EIC to the guest editor. At this point, the guest editor should notify the author(s) of acceptance. 8) Acceptance of papers for special issues of MPB are conditional on the viability of the issue. "Viability" is currently defined as a page count of at least 128. Once the page count of accepted papers reaches this threshold, all past and future acceptances for this issue become unconditional. In the event that acceptances for an issue exceed the capacity of a single issue, a multiple issue will be published. 9) Should an issue not reach viability, any papers that have been conditionally accepted for that issue will, with the consent of the authors, be forwarded to the EIC of MPA, along with referee reports and all relevant correspondence. Such papers may undergo further review at MPA; in this case, the review process will be expedited to the extent possible. The EIC of MPA will make the final determination as to acceptability of these papers for MPA. 10) Any submissions that are accepted for an issue of MPB but which do not appear in that issue (usually through failure to meet the deadline for submission of a revision) will, with the consent of the authors, be forwarded to the EIC of MPA, and will be subjected to the procedure outlined in (9).
