The purpose of this research was to planning to cultivate economic crops by developing mathematical models and algorithms to solve the problem of planning the selection to find appropriate areas for cultivate economic crops. To consider the economic value for farmers to receive the most profit by using sub-district level information in 8 provinces in the northeastern region of Thailand. The 3 types of economic crops are rice, cassava and sugarcane. This research developed a mathematical model and solved the problem by 3 methods i.e. the LINGO V.11 software, the Difference Evolution algorithm (DE) and Modified Difference Evolution algorithm using the Random best algorithm method (MDE-R). The results from the problem instances categorized into 3 groups showed that testing with small size instances using the LINGO V.11 software and the DE method both gave the same answer but the DE method took less time. When testing with medium size, large size, and case study instances by using the DE and MDE-R methods was found that the MDE-R method gave better answers than DE method at the equal time. The optimization of the highest profit was 12,760,520 baht per cycle.
