Hi All, I am new to R and want to use R to solve search problems (like Travelling salesman problem, finding nearest neighbour, hill climbing). Is this possible in R? To start with I want as follows. Find five float numbers whose sum is is equal to their product which should be 8000. x + y + z + p + r = 8000 x * y * z * p * r = 8000 Regards, Ambikesh Jayal.
