An algorithm for solving the classical linearprogramming problem; developed by George B. Dantzig in 1947.The simplex method is an iterative procedure, solving asystem of linear equations in each of its steps, andstopping when either the optimum is reached, or the solutionproves infeasible. The basic method remained pretty much thesame over the years, though there were many refinementstargeted at improving performance (eg. using sparse matrixtechniques), numerical accuracy and stability, as well assolving special classes of problems, such as mixed-integerprogramming.

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
