In computer science, there is the notion of the edit distance between two strings. 1  For example, the words dog and dot, which vary by only one letter, are closer than dog and cat, which differ by three letters. This idea is used in spell checkers and in coding theory, and is mathematically formalized in several different ways, such as: 1  Levenshtein distance. 2  Hamming distance. 3  Lee distance. 4  JaroâWinkler distance. 5  N-gram distance.
The Three Sisters. The traditional Native American planting of corn, beans and squash makes an ideal companion combination. Corn is planted first, and when it is tall enough to provide support, pole beans are planted next to each corn stalk. The beans provide nitrogen to the corn, and the corn provides a stalk for the beans to climb.
Beans are light feeders. Since beans are legumes they will fix nitrogen once a good root system is established; inoculation will speed the process. Excess nitrogen will delay flowering, so sidedress only after heavy bloom and set of pods, using l 1/2 ounces or 3 tablespoons of 10-10-10 per 10-foot row.nd of pod will be spongy. For dry beans (of all types) pods should remain on bush until dry and brown. Approximate yields: 3 to 5 pounds snap beans, 4 to 6 pounds lima beans per 10-ft. row. Amount to Raise: 8 pounds of snap beans, 5 to 10 pounds of lima beans per person.
