Perhaps you should try some spelling variations:
"modified exact convolution algorithmsss" » "modified exact evolution algorithm", "modified exact evolution algorithmss", "modified exact solution algorithmss", "modified exact solution algorithmsss"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
