CALL FOR PAPERS Announcing special STUDENT ISSUE of the International INTERVAL COMPUTATIONS Journal. Guest editors: Guenther Mayer and Vladik Kreinovich The future of Interval Computations is with the students researchers entering the field. Their vision, their insights, their approaches will shape the future research. To highlight their contributions, the Editorial Board of the Interval Computations Journal decided to make a special issue that will contain high-quality papers written by students (either alone, or in co-authorship with their professors). These papers will undergo the same refereeing as all the other papers. We will try our best to publish this issue as fast as possible. Papers authored or co-authored by students will be automatically entered into a Best Paper contest. The Editorial Board of the Interval Computations Journal will choose the winning paper. The student author of the best paper will be given a special certificate and a free one-year subscription to Interval Computations. Papers should be written in any version of TeX (preferably AMS-TeX).
