+ * The function selects one of the algorithms mentioned above based on:
+ *      - The size of the kernel
+ *      - Number of input/output feature maps
+ *      - Amount of memory needed
+ *
+ * Generally GEMM-based convolution is executed when neither Winograd nor FFT nor Direct convolution can be performed.
