PDA 3SAT Solver Please see http://www.pda-solver.com for product EULA This new Pressure Driven Algorithm (PDA) I have developed solves 3SAT problems well within Polynomial Time given that the number of Clauses is at least 7 times the number of inputs. The algorithm has been tested between 100 and 1638400 inputs with the number of Clauses equal to at least 7 x n. The results graph (main screenshot) shows the solve times compared with a Polynomial Time of n x E1.32 (where n is the number of inputs, and 1.32 is the polynomial time exponent). The solve times of my algorithm are clearly MUCH better than Polynomial time as the number of inputs increases - making solving large 3SAT problem easy & quick. This C source code can be adapted to your needs & does require some programming knowledge to use successfully. The main control parameters for the solver are few in number and #defined at the top of the file for easy configuration. The 3SAT problems that this algorithm solves need to be presented to the algorithm in an array expressed in 3 Conjunctive Normal Form (3CNF). The demo application available in the download showcases the algorithms solving capacity on randomly generated 3SAT problems over the whole range of tested inputs. 3SAT problem Encoding Format All SAT instances are of conjunctive normal form formula, i.e., the conjunction of clauses, where each clause is a disjunction of several literals. Suppose a formula given as (x7 + ~x1 + ~x6) (x6 + ~x7 + ~x4) (~x3 + ~x8 + x6) (x8 + ~x6 + ~x1) (~x10 + x2 + x8) (x5 + ~x6 + ~x4) (x1 + ~x7 + ~x6) (~x9 + ~x4 + x7) (x4 + ~x5 + ~x10) In the encoding format, this formula is stated as follows. # example of "data" array encoding used by PDA alogorithm code: 7, -1, -6, 6, -7, -4, -3, -8, 6, 8, -6, -1, -10, 2, 8, 5, -6, -4, 1, -7, -6, -9, -4, 7, 4, -5, -10]]>

Image Selector allows for the easy selection of image files - such as digital camera pictures.

Images can be selected from multiple source directories and saved into one or more destination directories for later use; such as: burning to CD, printing, emailing, archiving etc.

A large viewing window allows for easy identification of Images, and saving can be done at a single click, allowing for rapid, error free selections to be made. Images can also be rotated at a single click, or printed at A4 size.

Images can be selected under user control, or automatically using the slideshow feature which will display all images in the source directory in an endless loop, either forward or backwards and with a delay time between pictures selected by the user (default of 1 second). Images may be rotated, saved or printed during the slideshow, making selections from large numbers of images simple.

Currently a number of image formats are supported: jpeg/jpg/jpe, bmp/dib, gif, png, tiff/tif.]]>
