✦ Synopsis

Ireland (see application form in this issue) Nature of physicalproblem Find the symmetries of the given evolution equation: This is Computer: HITAC M-200H important because it enables us to know the qualitative nature of the equation and leads to physical insight. Operating system: VOS 3 Restriction on the complexity of the problem Programming language used: REDUCE 3.0, RLISP . The available computer storage is the severest restnction. High speed storage required: depends on the problem, minimum about 1000 Kbytes Running time It depends on the rank of the symmetry. It cannot be estimated No. of bits in a word: 32 in advance.
