MARXAN (SPEXAN)
• Develops a portfolio of reserve designs that meet particular targets.
• Uses simulated annealing to develop a large number of alternative designs.
• Attempts to minimize the total cost (boundary length) of the reserve network.
• Allows the analyst to control the spatial configuration of the reserve designs.
