A survey of divide and conquer algorithms for polygon fillings

This survey looks at five different polygon breaking algorithms and compares them. The criteria for comparison are: 1. Complexity of the algorithm. 2. The number and type of subpolygons produced. 3. The classes of input polygons that can be broken. The best algorithm is then coded and a comparison is made with con­ventional filling methods

A Papyrus Fragment with Mention of a Loan upon Mortgage

The papyrus preserves seven complete lines from the central part of a column.There is a left margin of 1 cm and a right one of 0.7 cm. The writing runs parallel to the fibres. The back is blank. On palaeographical grounds the papyrus could be ascribed to the fifth century A. D.; cf. BGU XII 2141 (446 A. D.; Plate 2a)
