CCL: Unsolved Problems

 Sent to CCL by: Michel Petitjean [petitjean.chiral-*]
 The following problems may be considered as mathematical ones, but
 they could be of interest for the computational chemist.
 Chirality (any measure you like):
 * Find the maximally (possibly asymptotic) chiral distribution of
 points in R^3 (discrete or continuous; no graph, no labeling).
 * Find the maximally chiral tetrahedron (non labeled set of 4 points).
 Remark: before defining your own chirality measure, please check that
 it makes sense at least in the simplest situations (e.g.
 unidimensional finite sets)
 Geometric docking (no charge):
 * Define a scale independant index taking values in [0..1] measuring
 the degree of geometric docking
 * Once defined, find non trivial shapes realizing the maximum of the
 index, then the minimum of the index
 Remark: the bidimensional case is of interest, too.

 problems facing industrial (and some academic) researchers that should be
 addressed.  There are others, but this should get things started.
