unimproved
3."What happens when you plant these trees is stiikingly different from what happens when you plant ordinary, unimproved trees."
4.Five nonlinear functions (three low-dimensional and two high-dimensional functions) are employed to test the performance and efficiency of five hybrid optimization algorithms, which are improved Logistic map based chaos-BFGS algorithm, Kent map based chaos-BFGS algorithm, unimproved Logistic map based chaos-BFGS algorithm, Monte Carlo-BFGS algorithm, and mesh-BFGS algorithm. The global optimization performance of these algorithms is compared, and the performance discrepancy of optimization algorithms is discussed.
